The Evolution of Jacob deGrom’s Training Routine from Rookie to Veteran

Since debuting with the New York Mets in 2014, Jacob deGrom has established himself as one of the most dominant pitchers in Major League Baseball history. With two Cy Young Awards, a career ERA under 2.50, and strikeout rates that regularly exceeded 11 per nine innings, his performance has been sustained at an elite level for nearly a decade. That kind of consistency does not happen by luck. It is the product of a training regimen that has evolved dramatically from his rookie season to his veteran years. Early in his career, deGrom relied on high-volume strength work and basic arm care. By his late 20s, he had shifted to a data-driven, injury-preventative approach. Today, as a veteran in his mid-30s, he follows a hyper-individualized program built on advanced biomechanics, precise conditioning, and meticulous recovery. This article breaks down each phase of his evolution, the science behind his methods, and actionable lessons for athletes at any level.

Early Years: Building a Foundation (2014–2016)

When deGrom was called up in May 2014 at age 25, he was already a veteran of adversity. He had undergone Tommy John surgery in 2010 while at Stetson University, a procedure that forced him to relearn proper mechanics and rebuild arm strength from the ground up. That early setback shaped his initial training mindset: focus on fundamental strength, durability, and volume to prove he could handle a starter’s workload.

In his first two full seasons, deGrom’s training was straightforward. He followed a conventional baseball strength program centered on compound lifts: barbell back squats, conventional deadlifts, and bench presses. These exercises built total-body strength but were not tailored specifically to pitching. His arm care routine included basic elastic-band exercises for the rotator cuff (internal and external rotation, shoulder extension), light dumbbell shoulder work, and long-toss programs that gradually increased distance. He also performed trunk rotations with a medicine ball and cable pull-throughs to develop rotational strength.

DeGrom’s results were solid — he posted a 2.69 ERA as a rookie and won the National League Rookie of the Year Award. However, the following season (2015) he struggled with a 3.54 ERA and a noticeable dip in fastball velocity, which fell from an average of 95 mph to 93 mph. He later admitted he was fatigued from the heavy workload and lack of individualized recovery. That experience prompted a major shift in his training philosophy.

During this early phase, deGrom also worked on refining his delivery. Video analysis showed he was rushing his arm action, causing him to open his front shoulder too early. He incorporated drills to improve hip-to-shoulder separation, such as towel drills and slow-motion arm actions in front of a mirror. These mechanical tweaks, combined with a renewed focus on arm care, set the stage for his breakout.

The Shift to a Structured, Data-Informed Program (2017–2019)

Between 2017 and 2019, deGrom transformed from a good pitcher into an elite one. His ERA dropped from 3.53 in 2017 to a staggering 1.70 in 2018, earning his first Cy Young Award. He followed that with a 2.43 ERA and 255 strikeouts in 2019, capturing a second Cy Young. This leap did not happen because of one magic bullet. It was the result of a complete overhaul of his training regimen, based on emerging sports science and personalized feedback.

Core Stability and Rotational Power Over Raw Strength

DeGrom abandoned heavy barbell lifts for exercises that targeted core stability and rotational power without loading the spine vertically. His new routine included single-leg Romanian deadlifts to improve hip stability and balance, Pallof presses for anti-rotation core strength, and medicine ball slams that emphasized explosive hip rotation. He also added isotonic exercises like cable chops and lifts to strengthen the obliques and transverse abdominis. The goal was not to get stronger in absolute terms, but to produce force more efficiently through his kinetic chain.

Velocity Gains Through Plyometrics and Mobility

deGrom’s average fastball velocity climbed from around 94 mph in 2015 to over 96 mph by 2018. This increase correlated with specific training changes. He began incorporating plyometric drills such as box jumps and weighted lateral bounds to improve leg drive and explosive power from the rubber. He also prioritized hip mobility, using dynamic stretches like leg swings and 90/90 hip rotations to increase his range of motion without compromising stability. According to research from Driveline Baseball, efficient force transfer from the lower body to the upper body is critical for velocity, and deGrom’s improved mobility allowed him to generate more speed with less mechanical stress.

Injury Prevention Becomes a Central Pillar

After missing time in 2016 with a strained latissimus dorsi, deGrom committed to a rigorous injury-prevention protocol. He began daily soft-tissue work with foam rollers and lacrosse balls, targeting the posterior chain (glutes, lower back, and lats). He also started a supervised weighted-ball program, which involved throwing weighted baseballs (4- to 6-ounce) to build arm strength while maintaining elasticity. This method, detailed in a MLB.com feature on his routine, was cutting-edge at the time. He also shifted his throwing philosophy from high volume to high quality: each bullpen session had a specific purpose (fastball command, slider depth, etc.), and he never threw more than 60 pitches in a side session.

The results spoke for themselves. deGrom threw over 200 innings in both 2018 and 2019, and his strikeout rate exceeded 11 per nine innings. He had become one of the most efficient and durable pitchers in baseball, largely because his training now prioritized staying on the field over lifting heavy weights.

Veteran Precision: The Current Routine (2020–Present)

By 2020, deGrom was in his early 30s and dealing with the cumulative toll of a decade of professional pitching. Recurring back tightness and side issues forced him to abandon any remaining “one-size-fits-all” approaches. His current training is built around four pillars: advanced biomechanics, personalized conditioning, nutrition optimization, and high-tech recovery. Each pillar is fine-tuned based on real-time data and his body’s feedback.

Advanced Biomechanics and Data Integration

deGrom now works with a team of trainers, physical therapists, and analysts who use motion-capture systems (including Edgertronic high-speed cameras and Rapsodo pitch tracking) to break down every element of his delivery. They monitor metrics such as:

  • Hip-shoulder separation timing – the angular difference between his pelvis and torso at foot strike.
  • Elbow angle at maximal external rotation – to ensure he is not exceeding safe ranges.
  • Trunk lateral flexion – to prevent excessive side bend that can load the spine unevenly.

If any parameter deviates by even two degrees, his team prescribes a specific corrective exercise. For example, if his shoulder drops at foot strike, he performs controlled arm-raise drills with a resistance band to reinforce proper scapular positioning. This micro-adjustment strategy allows him to preserve his release point and pitch movement while minimizing cumulative joint stress.

Personalized Conditioning: Less Volume, More Specificity

Gone are the days of heavy back squats and conventional deadlifts. deGrom’s current lifting program prioritizes core stability, posterior chain activation, and rotational power without loading the spine vertically. His staple exercises include:

  • Turkish get-ups – to improve shoulder stability and hip control through a full range of motion.
  • Banded lateral walks – to strengthen hip abductors and external rotators, crucial for maintaining leg drive without overstriding.
  • Single-leg box jumps – for explosive lower-body power asymmetrically, mimicking the push off the rubber.
  • Cable chops and lifts – to enhance anti-rotation control through the torso and prevent unnecessary trunk rotation.

His off-season throwing schedule is meticulously periodized. He begins in January with short, low-intensity sessions (30 pitches, all fastballs at 75% effort) and gradually builds to max velocity efforts by March, all tracked with a radar gun and feedback from his trainers. In-season, he typically throws one high-intensity bullpen per week (about 40-50 pitches), with the other days consisting of recovery throwing (light catch, flat ground work) to maintain feel without taxing his arm. Rest days are scheduled precisely to avoid overtraining while ensuring enough stimulation to keep his mechanics sharp.

Recovery Modalities and Sleep Hygiene

deGrom has become a vocal advocate for dedicated recovery. His routine includes:

  • Cryotherapy – whole-body cold exposure (3 minutes at -240°F) to reduce systemic inflammation after starts.
  • Contrast-water therapy – alternating hot and cold baths to flush metabolic waste from muscles.
  • Instrument-assisted soft-tissue work – such as Graston technique and Active Release Therapy, performed by a licensed massage therapist twice a week.
  • Compression boots – to improve circulation and accelerate muscle recovery in his legs.

Perhaps most importantly, deGrom prioritizes sleep quality. He aims for nine hours per night, often timing his sleep window to align with his natural circadian rhythm. He avoids screens for at least 30 minutes before bed and uses blackout curtains and white noise machines. Research from the Sleep Foundation confirms that adequate sleep reduces injury risk, improves reaction time, and enhances immune function — all critical for a starting pitcher.

Nutrition Optimization: Fuel for Elite Performance

deGrom’s diet has also evolved significantly. He works with a sports nutritionist who designs meal plans based on his training load, recovery needs, and inflammatory markers. A typical day during the season might include:

  • Breakfast: Oatmeal with berries, eggs, and a glass of tart cherry juice for antioxidant support.
  • Lunch: Grilled chicken or fish with quinoa, sweet potatoes, and a large leafy green salad.
  • Snack: Greek yogurt with almonds and a piece of fruit.
  • Dinner: Lean protein (beef or salmon), roasted vegetables, and brown rice.
  • Hydration: Electrolyte drinks before and after starts, plus monitoring urine color to ensure adequate hydration.

He also takes Omega-3 supplements (fish oil) and vitamin D3 to support joint health and immune function. During the season, he strictly avoids processed foods, excessive sugar, and alcohol. This nutritional discipline helps him maintain a steady energy level throughout the long season and accelerates recovery between starts.

The Role of Injury Prevention in Career Longevity

Despite his meticulous routines, deGrom has not been immune to injury. He missed significant time in 2021 due to right forearm inflammation and again in 2023 after undergoing surgery to repair the ulnar collateral ligament (UCL) in his throwing elbow. These setbacks have forced him to continually reassess what “prevention” truly means. His response to each injury has included longer ramp-up periods, more conservative workload management, and even greater emphasis on eccentric strengthening and pre-throw activation drills.

For example, after his forearm injury, he added exercises specifically designed to strengthen the flexor-pronator mass (the muscles that originate at the medial epicondyle and are often strained in pitchers). These include wrist curls, reverse wrist curls, and pronation/supination drills with a dumbbell or resistance band. He also incorporated the Tyler Twist, a common rehab exercise that targets the flexor carpi ulnaris. According to research from the American Sports Medicine Institute, the vast majority of pitching injuries stem from overuse and poor mechanical efficiency. deGrom’s proactive approach — never pitching through pain and immediately reporting any abnormal sensation — has allowed him to continue competing at an elite level even as he enters his late 30s.

He also uses wearable technology like the Motus sleeve, which measures elbow torque and arm speed during throwing. If the data shows excessive torque, he will scale back his intensity in the next session. This data-driven caution is a hallmark of his veteran approach.

Lessons for Aspiring Athletes and Coaches

Jacob deGrom’s training evolution offers a blueprint for athletes in any sport. Several key takeaways stand out:

Adapt Your Training as You Age

What works for a 25-year-old rookie does not work for a 32-year-old veteran. deGrom’s progression from high-volume strength training to a more tailored, data-driven program shows that routine must evolve with physical changes, injury history, and performance goals. Young athletes should build a solid all-around foundation, but be ready to pivot as their bodies mature and as they learn more about their individual needs. A 20-year-old can handle heavy squats and high-repetition throwing; a 30-year-old needs more emphasis on mobility, eccentric strength, and recovery.

Data Is a Tool, Not a Crutch

deGrom uses advanced analytics to inform his decisions, but he does not let numbers dictate every move. He blends objective feedback from biomechanics and pitch tracking with subjective feel from his own body. If the data says his hip-shoulder separation is optimal but his arm feels dead, he will adjust accordingly. The best athletes marry science with self-awareness. Coaches should teach athletes to interpret data critically and listen to their bodies.

Prioritize Recovery as Much as Training

Cryotherapy, massage, sleep, nutrition — these are not luxuries but necessities for high performance. Many athletes focus only on the “grind” and ignore recovery. deGrom’s career longevity highlights that the best training plan can be undone by inadequate recuperation. Athletes should schedule recovery as rigorously as they schedule workouts. For example, after a high-intensity session, the next day should be dedicated to active recovery (light mobility, foam rolling, low-impact movement) rather than another hard workout.

Be Willing to Make Hard Tradeoffs

deGrom often chooses to skip non-essential workouts or take an extra rest day rather than push through fatigue. He has also turned down lucrative endorsement deals that required promotional appearances during the season because they interfered with his routine. Prioritizing performance over short-term gains is a hallmark of a true professional. Athletes should regularly evaluate their schedule and eliminate anything that does not directly contribute to their sport-specific goals.

Injury Prevention Is an Ongoing Process

Even with the best protocols, injuries can still occur. deGrom’s experience shows that prevention requires constant monitoring and adjustment. After each injury, he did not just return to his old routine; he added new exercises, increased his warm-up time, and refined his mechanics. Athletes should treat their bodies as dynamic systems that require regular maintenance and fine-tuning.

Conclusion: The Athletic Evolution of a Cyclone

Jacob deGrom’s journey from a raw, high-volume arm to a precise, science-backed veteran is a model of intelligent adaptation. He has not just survived in the majors — he has dominated, rewriting record books for pitchers in their 30s. By constantly questioning his methods and embracing new knowledge from sports science, he has extended his peak while staying ahead of the inevitable decline that comes with age. For anyone serious about athletic performance, his training evolution is not just interesting — it is instructive. Study it, adapt its principles, and you too can build a career that lasts far beyond the typical shelf life.
