have you ever tried the power balance band during training, sparring, or running?


if you do, do you notice any improvement or at least maintain your strength for the rest of your time training?
am interested with this thing, but i dont trust those testimonials in the net or ads coz thats a plain ads and they would be dumb to putting negative comment on the brand
just want a real experience to those who use it. thanks.
