quadriceps·legs

Isometric knee press

Sit with one leg straight, a rolled towel under your knee. Press the back of your knee DOWN into the towel as hard as you can. Hold 5 sec. Release. 10 reps per leg, 2× a day. Strengthens the quadriceps without joint movement — ideal for hypermobility (EDS), post-op knee, or anyone who locks their knees passively standing.

Secondary muscles

hamstrings

Form cues

1Press DOWN HARD — this is maximum-effort isometric, not a light squeeze
25-sec hold; 5-sec full release between reps
3Feel quad on FRONT of thigh firing — not just hamstring

Common mistakes

Lifting the heel off the floor (lifts the leg, defeats the isometric)
Soft press — full strength is the whole point
