Video Summary - It's weird, but Tendon training will give you jaw-dropping strength

Key ideas from the video: why tendon training matters for strength + longevity

Tendons transfer muscle force to joints. If tendons can’t handle the load, your strength gains won’t fully express where you need them.
Tendon function improves efficiency. Tendons act like springs—helping recycle mechanical energy during walking/jumping and making movements more efficient.
Grip strength is strongly linked to lifespan, and it depends heavily on forearm muscles + tendons.
Stretching doesn’t significantly “lengthen” tendons. It may improve flexibility, but tendon strength adaptations mainly come from loading tendons.

Don’t just “work harder” in the gym. Build in recovery and targeted tendon loading, because:
- Tendons adapt slower than muscles.
- If you ramp muscle work too fast, you can get tendon injuries (example given: Achilles ruptures after a league shutdown).
- In gym studies, failure training may strengthen muscles, but may not provide enough tendon-specific strain.

Use these categories to guide programming:

Long, heavy isometric holds
- Best for: sustained near-max strain (like pushing/pulling against something immovable).
- Why it works (from the video): tendon adaptation needs high sustained tension, not just brief peaks.
Heavy slow resistance (slow eccentrics / controlled reps)
- How: use a similar weight to normal lifting, but lower for 3 seconds + lift for 3 seconds (slow tempo).
- Why it works: triggers tendon remodeling (collagen-related changes).
Reactive / explosive training
- Examples: jumps, depth jumps, stretch-shortening exercises.
- Goal: build ability to “snap back” faster by increasing tendon stiffness and elastic energy return.
- Timeline mentioned: noticeable changes after ~12 weeks.
Nutritional support: gelatin + vitamin C (timed before exercise)
- What: ~15g gelatin + vitamin C about 1 hour pre-workout.
- Why (mechanism suggested): provides amino acids for collagen production and may boost collagen synthesis during tendon loading.
- Note: not presented as the “best” sole strategy—more like an add-on.

The video recommends adding 2 of these into your normal training:

Eccentric heel drop (Achilles tendon)
- Raise up on both toes, shift to one leg, slowly lower the heel 3–5 seconds with a straight knee.
- Push back up using the non-working leg.
- Key stimulus: controlled slow lengthening under load.
Isometric wrist extension hold (tennis elbow / tendon irritation)
- Palm down under a table; push upward against the table without letting the wrist move.
- Use a structured program concept: ~8 weeks, start light and build intensity/duration.
- Video claims it outperforms simply waiting for pain to go away.
Weighted dead hang (fingers + forearms grip tendon strength)
- Grip a pull-up bar with an open hand (avoid curling too tightly to prevent finger tendon strain).
- Keep shoulders packed (not “dangling”).
- Progressions:
  - Baseline: around 1 minute hold (average).
  - Set example: 7 seconds hang / 3 seconds rest x 6 reps
  - Progress by increasing hang time → smaller edges → then add weight (vest/belt).
Nordic hamstring curl
- Anchored ankles, straight line from knees/hips/shoulders, slight chin tuck.
- Slowly resist the forward fall with hamstrings as long as possible, then catch with hands to return.
- Video cites reduced hamstring injury rates in soccer teams (with some caveats about research strength).

Stop overtraining the way people often do (“come into the gym… at least twice a day” / “not good for your tendons”).
Focus on recovery alongside tendon-focused work.
