How to Train Your Hamstrings Effectively

Introduction

Hamstring injuries are among the most prevalent in sports, accounting for 12-16% of all injuries in elite football (Ekstrand et al., 2011) and a leading cause of time lost in sprint-based sports. Additionally, research suggests that hamstring strength is a key predictor of sprint performance, with elite sprinters exhibiting 20-30% greater eccentric hamstring strength compared to sub-elite athletes (Timmins et al., 2016). Given these statistics, a structured and research-backed approach to hamstring training is essential. To train your hamstrings effectively, you must go beyond traditional strength exercises and incorporate a well-rounded strategy backed by scientific evidence. This article explores five key principles for optimal hamstring development, supported by peer-reviewed medical and sports science literature.

1. Prioritise Heavy Eccentric Exercises

Eccentric training (lengthening contractions under load) is a gold-standard method for reducing hamstring injuries and improving performance. Nordic hamstring curls have been widely studied for their ability to enhance eccentric strength and reduce injury risk.

Why Eccentric Training?

• Research by van Dyk et al. (2019) found that teams using Nordic hamstring curls reduced hamstring injuries by up to 51%.

• A systematic review by Al Attar et al. (2017) concluded that eccentric hamstring exercises significantly lower the risk of re-injury, particularly in football and sprint-based sports.

Best Eccentric Hamstring Exercises

• Nordic Hamstring Curl: Proven to increase fascicle length and eccentric strength (Presland et al., 2018). It's important to sufficiently load your hamstrings are in a lengthened position (when you're close to hitting the floor). I like to assist athletes with a band to make this exercise more effective.

• Romanian Deadlift (RDL): Strengthens hamstrings through hip extension while improving control over the eccentric phase. Try doing a staggered or B stance RDL to ensure you are loading each leg equally.

• Sliding Hamstring Curls: Engages hamstrings through both knee flexion and hip extension. If you don't have sliders, wooly socks on timber flooring will work fine.

2. Incorporate Both Hip-Hinge and Knee-Flexion Based Exercises

Hamstring function involves two main movements: hip extension (e.g., during deadlifts) and knee flexion (e.g., during leg curls). Research suggests training both movements for optimal strength and resilience.

Evidence Supporting Combined Training

• A study by Bourne et al. (2017) found that both hip-dominant (RDLs) and knee-dominant (Nordic curls) exercises improve hamstring muscle architecture, reducing injury risk.

• Timmins et al. (2016) found that longer hamstring fascicles from combined training are linked to lower injury rates.

Best Exercises for Each Movement

• Hip-Hinge Based: Romanian deadlifts, Good mornings, Hip thrusts

• Knee-Flexion Based: Nordic hamstring curls, Lying hamstring curls, Swiss ball leg curls

3. Develop Power and Robustness with Plyometrics

Plyometric training enhances the hamstrings’ ability to generate force quickly and absorb high-impact loads, essential for sprinting, jumping, and agility.

Scientific Backing for Plyometric Training

• Lacome et al. (2020) highlighted that plyometric drills improve hamstring stiffness and force absorption, reducing the risk of sudden overload injuries.

• Markovic & Mikulic (2010) demonstrated that explosive plyometrics enhance rate of force development (RFD) in lower limbs, critical for sprinting and jumping.

Effective Plyometric Drills for Hamstrings

• Bounding & A-Skips: Enhances hamstring stiffness and sprint mechanics.

• Hamstring Tantrums: Works on producing speed and power in the proximal range. For this exercise you lie on your stomach. You can use either a Swiss Exercise ball or a Resistance band tied around a secure squat rack. 

• Resisted Broad Jumps: Builds horizontal power output, which is sprint-specific.

4. Expose Yourself to Top Speed Running

Sprint exposure is often neglected in injury prevention programs. Research has shown that most field-based athletes do not expose themselves to top speed running on a weekly basis. However, sprinting at maximal velocity is one of the most effective ways to strengthen the hamstrings dynamically.

Why Sprinting is Essential

• Mendiguchia et al. (2020) showed that sprinting recruits the hamstrings at high force outputs, making it crucial for sport-specific conditioning.

• Schache et al. (2012) confirmed that the hamstrings experience their greatest eccentric loads during the late swing phase of sprinting.

Sprint Training Guidelines

• Include maximal sprint efforts (≥90% of top speed) 1-2 times per week.

• Progressively increase sprint volume to reduce injury risk and improve sprint mechanics.

• You can also consider using resisted sprints (sled drags) to strengthen the posterior chain further. However, this should not be considered top speed running.

5. Train Supporting Muscle Groups: Core, Glutes, Hip Adductors, and the Calf Complex

Hamstring health is also influenced by synergistic muscles that support lower-limb function. Weak core, glutes, hip adductors, or calves can shift excessive load to the hamstrings, increasing injury risk. The good news is that we can incorporate core strengthening exercises into a lot of lower limb exercises, reducing the need for a long list of exercises. 

Scientific Support for Accessory Training

• Mendiguchia et al. (2015) found that weak glute max activation correlates with hamstring overuse and strain injuries.

• De Ridder et al. (2021) emphasized adductor training to balance hip mechanics and reduce strain on the hamstrings.

• Ruggiero et al. (2019) showed that calf strength deficits contribute to lower-body instability, indirectly affecting hamstring resilience.

• A systematic review by Al Attar & Husain (2023) found that core strengthening exercises reduced hamstring injury risk by 47%.

Key Exercises for Synergistic Muscles

• Glutes: Hip thrusts, Bulgarian split squats, Step ups

• Adductors: Copenhagen planks, Lateral lunges

• Calves: Soleus & gastrocnemius raises (bent and straight leg calf raises), Pogo jumps

• Core muscle strengthening exercises: Single leg hip thrust, Copenhagens, Swiss ball Hamstring roll-outs.

6. Proprioception and Its Link to Hamstring Injuries

Proprioception refers to the body's ability to sense movement, position, and force. Think of it like this, even with your eyes closed, if someone was to bend your knee, you would know it is now in a bent position. This is of course, an oversimplification of what proprioception is. The hamstrings, crossing both the hip and knee joints, require precise coordination to function efficiently. Deficits in proprioception increase the likelihood of hamstring injuries by impairing balance, joint stability, and neuromuscular timing, leading to excessive load on the muscles during high-speed activities such as sprinting and sudden direction changes (Huang et al., 2021).

Evidence-Based Benefits of Proprioceptive Training

A study by Freeman et al. (2022) demonstrated that athletes undergoing proprioceptive retraining had a 30-50% lower risk of hamstring reinjury compared to those receiving conventional strength and flexibility training alone. This reduction is attributed to improved neuromuscular control, which optimizes muscle activation patterns and reduces erratic joint movements that place excessive stress on the hamstrings.

Another systematic review by Hrysomallis (2023) found that proprioceptive training enhanced lower limb coordination, decreased reaction time to perturbations, and reduced injury recurrence in previously injured hamstrings by 40-60%. This aligns with research highlighting that poor postural control and proprioceptive deficits are major risk factors for hamstring strains.

Proprioceptive Exercises for Hamstring Injury Prevention

• Single-leg stance on unstable surfaces (e.g., BOSU ball, foam pad) to enhance balance and neuromuscular coordination. A single leg RDL can be a great way of loading the hamstrings and incorporating proprioceptive training.
• Perturbation-based training (e.g., resisted band drills, reactive agility drills) to improve rapid corrective responses.
• Cognitive-motor dual-task drills, such as balancing while performing visual tracking tasks, to enhance sensorimotor integration.

Conclusion: A Holistic Approach to Hamstring Training

To effectively train your hamstrings for injury prevention and athletic performance, you need a multi-faceted approach:

• Prioritise eccentric loading to build resilience and prevent strains.
• Incorporate both hip-hinge and knee-flexion exercises for complete muscle function.
• Use plyometrics to improve power, robustness, and force absorption.
• Expose yourself to top-speed running to strengthen hamstrings dynamically.
• Train synergistic muscle groups to support lower-body mechanics and reduce compensation patterns.
• Integrate proprioceptive training to improve neuromuscular control.

By integrating these evidence-backed strategies, you’ll build hamstrings that are not only strong but also resilient, explosive, and ready to perform at an elite level. In defiance of Adequacy.
