I saw a post recently on this site about CIA's Extreme Intervals #2101. Does anyone know how it compares to Cathe's Interval Max tape? The only other tape I've ever seen compared to I-Max is Gin Miller's "Intense Moves", and I found that much more moderate than I-Max.
Has anyone done both I-Max and Extreme Intervals?
