Input:
Excellent. Truly excellent. I am no longer to able to do typical cardio exercises due to back and foot injuries. Callanetics are what I am working on instead these days, and these straps (I ordered two) really help me maintain many of the stretch and toning exercises that, as a beginner, I find very difficult to do. I won't stretch or do my callanetics without these now.
