I'm currently doing meso 2. I love this rotation, and while it really destroys your body parts I have been waiting 2-3 days and then repeating a body part on an off day..combining it with an ab workout. It seems that all the related groups are only hit once then rest for a week.For instance on tues combine bi's and abs Thursdays chest and shoulder and abs On wed after legs max out on pull ups etc. Has anyone else had any experience with this? I feel that I am so trashed by the end of some of these workouts that some parts don't get a fair shake! After all that I will say that after leg day I am NOT ready for a week! It takes that long to learn to walk again!!
