TENDON REHAB ADVICE
Isometrics are great. I will never argue against them.
Easy to load, easy to repeat, hard to get wrong. For tendon rehab especially, they have a genuine place and real value.
But here is the problem I keep seeing.
People do isometrics, pain settles, they feel good. Then they try to return to something more demanding and the tendon flares straight back up. So they go back to isometrics. Pain settles again. And the cycle repeats.
Sound familiar?
The issue is not the isometrics. The issue is the lack of progression and the way people are thinking about tendon rehab as a whole.
Two things need to change.
One. Isometrics still need to progress.
Longer holds. More load. Harder variations. Faster overcoming isometrics at a hard or near maximal effort. If you are doing the same hold at the same weight for the same duration week after week, you are not progressing. You are just managing.
Two. Stop thinking in steps. Start thinking in dials.
The biggest mistake in tendon rehab is treating it like a linear checklist. Isometrics first, then isotonic work, then plyometrics.
It does not work like that.
Think of each category as a dial with its own volume you can turn up or down depending on where you are in your rehab.
Early stage, your dial might look something like this:
π Isometrics: high volume, the foundation of everything right now
π Isotonic: low volume, introducing it carefully
π Plyometrics: minimal or none yet
As you progress, those dials shift:
π Isometrics: 15 to 20%, still in the background but no longer the focus
π Isotonic: dominant, building genuine strength through range
π Plyometrics: coming in, starting to prepare the tendon for real demands
And then they shift again as you move closer to full return to sport or running.
The tendon needs all three. The skill is in knowing how much of each, and when.
If your tendon rehab has stalled or you keep hitting the same wall and want long lasting results.
