THE BEST TRX CORE MOVE There's hundreds of core moves that you can do but you judt cannot beat the knee tuck because of two things. 1. The overall core engagement But also 2. The isolation of the top layer of abdominals purely through the lifting of the hips combined with bending of the knee. It's the bending of the knee at the same speed of the hips that's key. If you snap the knees, you're hiding from the pain and the real love of the movement. You'll hate me... Then you'll love me.
