Does this sound like the set of challenges you might be facing?

• I keep tweaking my hamstring every time I sprint, and I’m scared to open up at full speed because I’m always bracing for the next pull
• I get fired up and pile on way too much way too fast, and then a few weeks later I’m nursing some nagging tweak that sidelines me
• I’ve gotten more flexible but it feels fragile
• My Achilles has been sore and stiff for months and resting it does nothing
• Every time I try to squat low my heels lift off the floor and I tip backward

Practices that may help

1. Nordic hamstring curl for injury prevention
   A bodyweight eccentric exercise that dramatically cuts hamstring strain risk.
   Eccentric Training, Made Practical
2. Apply the 10% rule to limit weekly load increases
   Increase weekly training load (volume or intensity) by no more than 10% from the prior week to stay ahead of injury risk.
   Progressive Overload
3. End-range loading (strength through full range)
   Train muscles at end range of motion so new flexibility becomes strength, not vulnerability.
   Mobility Training, Made Practical
4. Eccentric loading for tendon rehabilitation
   Controlled eccentric load is the primary evidence-based stimulus for repairing tendinopathy.
   Eccentric Training, Made Practical
5. Ankle dorsiflexion work
   Restore the ankle bend that governs squat depth, gait mechanics, and knee tracking.
   Mobility Training, Made Practical
6. Progressive ruck march load/volume programming
   Increase either load or duration each week, never both — the most common programming mistake in rucking is loading too quickly.

7. Isometric holds as a bridge into eccentric work
   Isometric pauses in the lengthened position prepare tendons and muscles for heavier eccentric load.
   Eccentric Training, Made Practical
8. The back squat as the foundation of lower-body strength
   Squatting to depth under a barbell trains more muscle mass simultaneously than any other lower-body movement.
   Compound Movements: The Foundation of Strength Training
9. Taper before a target event to allow full supercompensation to express
   Cutting training load 1–3 weeks before an event allows accumulated adaptations to fully express — this is not detraining.
   Supercompensation
10. Consolidate and celebrate after a stretch goal is reached
    After hitting a stretch target, take time to stabilise the new level before stretching again.
