OK but I'll cheat and group my Powerstikes as one
1) Any Powerstrike..but the newest are the best.
2) Tie between Sherri J's Fit to Kick and Debbie B's TKO. Oops..another cheat..a two-fer
3)Cathe's Cardio Kicks...even though I consider it more Hi/Lo than kickboxing..but it gets brownie points for the drills at the end, it's actually one of the few KB tapes that gives me good doms in the upper back after the workout.
