Sore muscles, back pain (tendon)

I've been a ZenPad tester from the very beginning and use the ZenPad NoPain C va. on Back (vision and ligaments) and knees as stabilizers and the ZenPad NoPain A on the thighs when skiing to prevent sore muscles. The knee pain (tendons) on exertion is gone and it no longer occurs on the back.

The ZenPad NoPain A I apply it directly to both thigh muscles before skiing - in this case without a plaster but simply under my functional ski underwear. This helps me to maintain my strength for longer and prevents sore muscles.
