I just received a copy of Mike Mahler's new DVD Aggressive Strength. Mike has done an outstanding job with this instructional DVD. While I am a beginner to kettlebell training and clubbell training, Mike's program does an excellent job providing fundamental instruction in the proper execution of core exercises. His tips and insight provide the difference bewteen experimenting and discovery and getting right down to business.This DVD will see some extensive use and will be a cornerstone in my library of instructional videos. I would recommend picking up a copy.
