FitCord Resistance Bands 4-Pack (12lb/18lb/25lb/40lb)
Have had these bands for a few weeks. Really impressed with the quality. The band cover is nice too.
From all the bands out there (besides the B-Lines) these ones are the ones compatible with P90X, the other ones are just to light. These FIT CORD resistance bands go from 8lbs to 55lbs.According to P90x men should use 20,30,40 lbs and women should use 15,20,30 lbs. It's Just Great!!! same bands, less expensive, I already bought my set ;-)
we use these for P90x and will probably buy more for the workout. Really work well
