Like Linda aka Cruncholi, I use my body bar (also a challenge pro bar) for many other videos when my barbell just gets too heavy, especially during an endurance workout.
If you really want to get one, you'll find additional uses for it. I learned how to do crazy 8's using my 18# body bar. For whatever reason, I could complete the sets with Cathe if I used it rather than my barbell? Don't know if it was the even distribution of weight, or what, but I could not complete crazy 8's until I trained with the body bar.
I DO NOT use it for a weight on PS Legs when Cathe and the crew use theirs for the floorwork. I'm fine without weight thank you very much, but I do use it as a prop many times for calf raises in Leaner Legs, calf raises and plie squat warm up in PS Legs, also I use it sometimes in circuit workouts because it's just really handy.
So you could get your money's worth if you get one.
