Do you feel like your inner thigh/groin muscles are always tightening up when you run or lift?
This is sometimes caused by weakness in the outer hip (gluteal muscles – “side butt”). To help correct this, try to first stretch out your inner thigh and follow it with isolated lateral hip strengthening. The Adductor Rocks and the Clam Planks demonstrated in the video are one way to accomplish this.
Adductor Rocks: 5sec holds, 8-10x
Clam Planks: 5-10sec holds, 2×10
