Should you focus on isometrics? Are eccentrics the gold standard? Or should you be doing heavy concentric and eccentric strength work?In this episode, Brodie breaks down the different types of muscle contractions and, more importantly, explains how to combine them into a practical weekly PHT rehab routine.You’ll learn why isometrics can be particularly useful for pain relief and tendon stress relaxation, why eccentric-only training doesn’t appear to have a unique advantage over combined concentric and eccentric loading, and why the amount of load you can safely tolerate may matter more than the contraction type itself.Brodie also explains how your rehab should evolve as symptoms settle and capacity improves, moving from frequent, lower-load isometrics toward heavier and more functional strength training.In this episode:Isometric vs concentric vs eccentric contractions explainedThe two major benefits of isometrics for PHTKeith Baar’s concepts of stress shielding and stress relaxationWhy 20–30 second isometric holds can provide a useful tendon stimulusWhy eccentrics aren’t necessarily the “magic bullet” for tendon rehabWhen eccentric-biased exercises may still be particularly usefulWhy heavy loading appears more important than the specific contraction typeHow to use pain and next-day symptoms to guide progressionWhen to progress from isometrics into heavier movement-based exercisesHow to structure your rehab using a High → Low → Moderate → Rest approachHow running, cardio, recovery and individual goals fit into your weekly routineExample weekly structure:Monday – HIGHHeavy strength work such as deadlifts, step-ups and hamstring curls. Typically around 3 sets of 6–8 challenging repetitions.Tuesday – LOWLower-load isometrics using the Keith Baar-style protocol: approximately 3–4 sets of 20–30 second holds with 2 minutes rest.Wednesday – MODERATESimilar strength exercises to Monday, but at roughly 70–75% of your heavy-day load. This may also be an opportunity for some light running or cardio.Thursday – REST / RECOVERYRest or very light activity that places minimal demand on the tendon.From there, you can repeat the High → Low → Moderate → Rest cycle, or adapt the concept into a seven-day schedule based on your symptoms, running, equipment, recovery and goals.The key takeaway:Rather than searching for one perfect contraction type, focus on finding the combination of exercises that allows you to progressively expose the tendon to meaningful load without aggravating your symptoms.Keep coming back to three simple pain rules:Keep pain during exercise below roughly 4/10.Symptoms should return to your usual baseline by the next morning.Your overall symptoms and capacity should be improving week by week.Your ideal routine will depend on your current symptoms, capacity and goals, but the underlying principle remains the same: challenge the tendon, give it time to recover and adapt, then progressively challenge it again. ----------------------------------------------------------------MEDICAL & EDUCATIONAL DISCLAIMERThe information provided in the Overcoming Proximal Hamstring Tendinopathy (PHT) Podcast, YouTube channel, associated websites, social media, and other educational content produced by Brodie Sharpe is provided for general educational and informational purposes only.

How do you know whether you're pushing hard enough or too hard with strength training? And what role do age, hormones, stress and the nervous system play when symptoms just won't settle?Brodie also explores several tricky diagnostic presentations, including PHT that hurts with sitting but not running, sciatic nerve involvement, pain behind the knee, previous hamstring avulsions and why PHT is still so commonly mistaken for conditions such as piriformis syndrome, lumbar pathology and deep gluteal syndrome.Topics covered include:How to know whether you're loading your tendon too much or not enoughThe three key pain and progression rules Brodie uses during PHT rehabWhether PHT can still improve after 30+ yearsWhy chronic tendon degeneration doesn't necessarily prevent a full return to functionThe "treat the donut, not the hole" approach to degenerative tendonsHow chronic pain, hypervigilance and nervous-system sensitivity can influence symptomsWhether age significantly slows tendon recoveryHow rehab may need to change for someone in their 60sPerimenopause, menopause, estrogen and progesterone: what we currently know about tendon healthWhether hormonal fluctuations could explain sudden PHT flare-upsPsychological stress, pain sensitivity and recoveryThe current evidence for low-level laser therapy / photobiomodulationNutrition considerations for tendon recovery, including protein, collagen and vitamin CWhether it can still be PHT if sitting hurts but running doesn'tSciatic nerve involvement and when nerve mobility exercises may be usefulWhy pain behind the knee warrants further investigationWhether PHT needs to be tender when you press directly over the tendonThe possible relationship between a previous proximal hamstring avulsion and later gluteal tendon problemsWhy PHT is still frequently misdiagnosedWhy greater awareness of PHT among clinicians and patients mattersThroughout the episode, Brodie reinforces an important principle: rehab progression should be based on how your body responds, rather than arbitrary timelines.Keep symptoms mild during exercise, make sure they return to baseline by the following morning, and look for an improving trend from week to week. ----------------------------------------------------------------MEDICAL & EDUCATIONAL DISCLAIMERThe information provided in the Overcoming Proximal Hamstring Tendinopathy (PHT) Podcast, YouTube channel, associated websites, social media, and other educational content produced by Brodie Sharpe is provided for general educational and informational purposes only.

We cover some of the most common challenges during proximal hamstring tendinopathy recovery—from knowing when you're ready to start running again, to understanding why the tendon can still flare even when your strength exercises are completely pain-free.Brodie also discusses how to structure strength and cardio during rehab, progressing walking, the role of step-ups, hamstring curls and Nordic curls, and how to safely introduce faster running and sprinting. We then tackle the bigger return-to-performance questions, including HYROX training, racquetball, marathon preparation and reducing the risk of PHT returning.Topics covered: How long should you strengthen before returning to running?  Why can running still flare PHT when strength training is pain-free?  How to build tendon capacity as your running load increases  What should a weekly strength + cardio routine look like during PHT rehab?  When walking, should you progress duration, speed or incline first?  Why Brodie recommends weighted step-ups for PHT  Heavy hamstring curls: helpful or harmful?  Can Nordic curls and home exercises replace gym-based strengthening?  How to safely return to strides, faster running and sprinting  Training for HYROX while managing persistent PHT  How to decide when you're ready to return to sport  What determines whether a previously torn hamstring tendon is ready for marathon training?  If you could choose one strength exercise to help prevent PHT returning, what would it be? Whether you're just beginning PHT rehab or you're pain-free and trying to rebuild towards your previous running and sporting performance, this episode will help you understand how to progress without being unnecessarily held back by fear of flare-ups. ----------------------------------------------------------------MEDICAL & EDUCATIONAL DISCLAIMERThe information provided in the Overcoming Proximal Hamstring Tendinopathy (PHT) Podcast, YouTube channel, associated websites, social media, and other educational content produced by Brodie Sharpe is provided for general educational and informational purposes only.

But while your tendon is responding and rebuilding, nutrition may help provide the ingredients it needs to support that process.In this episode, I break down a new 2026 paper titled Rehabilitation Nutrition for Tendon and Ligament Injuries: From Collagen Remodelling to Return to Activity and Sport.We explore what the latest research says about energy availability, protein, collagen + vitamin C, creatine, vitamin D, calcium and omega-3s — including where the evidence is strong and where it remains more theoretical.In This Episode:Why progressive tendon loading remains the foundation of recoveryHow low energy availability could interfere with collagen remodelling and your ability to tolerate rehabWhy simply eating more protein isn't enough to heal a tendonThe recommended 1.6–2.2 g/kg/day of proteinWhy spreading protein throughout the day may be beneficialThe difference between traditional protein sources and collagen-specific amino acidsHow collagen + vitamin C may support collagen synthesis around your rehab sessionsMy practical collagen protocol: ~30 g collagen + 50–100 mg vitamin C, 30–60 minutes before tendon loadingWhy the loading stimulus that follows the collagen mattersHow creatine (3–5 g/day) may indirectly support tendon rehab by helping maintain muscle mass, strength and training capacityThe role of vitamin D and calcium, particularly when you're deficientWhy a food-first approach should generally come before supplementationHow omega-3 fatty acids may support the resolution of inflammationWhy nutrition should support your rehab rather than replace progressive loadingPractical TakeawaysProtein: 1.6–2.2 g/kg of body weight per day, ideally spread throughout the day.Collagen + Vitamin C: Around 30 g collagen with 50–100 mg vitamin C, taken approximately 30–60 minutes before an appropriate tendon-loading session.Creatine: Approximately 3–5 g/day.Calcium: Approximately 1,000–1,200 mg/day from dietary sources and/or supplementation when intake is inadequate.Vitamin D: Focus on achieving sufficient levels, particularly if you're deficient or have limited sun exposure.Omega-3s: Approximately 2–3 g/day of combined EPA + DHA may be considered when dietary intake is insufficient.Most importantly, don't become distracted by the 1% strategies while neglecting the fundamentals.Load the tendon appropriately. Eat enough. Get enough protein. Then start looking at the additional strategies that may help optimise the recovery environment.Nutrition isn't a replacement for good tendon rehab, but when you're dealing with a stubborn condition like PHT, it makes sense to ensure you're giving your body the resources it needs to adapt. ----------------------------------------------------------------MEDICAL & EDUCATIONAL DISCLAIMERThe information provided in the Overcoming Proximal Hamstring Tendinopathy (PHT) Podcast, YouTube channel, associated websites, social media, and other educational content produced by Brodie Sharpe is provided for general educational and informational purposes only.

Instead, we look at what scientists are discovering about tendon healing, how convincing the evidence currently is, and whether these approaches could eventually have a role in treating stubborn conditions like PHT.In this episode:Immune therapy & “smart scaffolds”Why inflammation isn't necessarily the enemy during tendon healingHow researchers are developing hydrogels and scaffolds that can respond to the tendon environmentThe potential role of exosomes in regulating inflammation and collagen repairWhy this technology is fascinating—but still a long way from routine PHT treatmentOxygen–ozone therapyWhat an ozone injection actually isHow a small amount of oxidative stress may trigger a beneficial biological responseA striking tennis-elbow study where 92.8% of the ozone group had favourable resting-pain outcomes at nine months, compared with 39.5% following corticosteroidWhat animal research suggests about ozone and tendon strengthWhy the evidence is still too limited to recommend it for PHTPhotobiomodulation / light therapyHow red and near-infrared light may influence the mitochondria inside tendon cellsWhy different wavelengths and doses matterAnimal research showing approximately:40% lower inflammatory markers65% greater markers associated with inflammation resolution1.7× better type-I-to-type-III collagen ratio20% greater tendon tensile strengthWhy these impressive laboratory results don't yet mean you should buy a red-light device for PHTThe key message:These treatments all approach tendon healing differently, but they share an important idea: future tendinopathy treatment may involve improving the biological environment of the tendon alongside progressive rehabilitation.For now, there isn't enough evidence to recommend any of these approaches specifically for proximal hamstring tendinopathy.So while researchers continue exploring the weird and wonderful future of tendon healing, stick with the fundamentals that we know work: appropriate load management, progressive strengthening and gradually rebuilding tendon capacity. ----------------------------------------------------------------MEDICAL & EDUCATIONAL DISCLAIMERThe information provided in the Overcoming Proximal Hamstring Tendinopathy (PHT) Podcast, YouTube channel, associated websites, social media, and other educational content produced by Brodie Sharpe is provided for general educational and informational purposes only.
