So, as a personal trainer im constantly coming up with new routines to keep things fresh and keep the world of muscle confusion at full throtle. I came up with this weekly body split for those of which (like myself) who got in that cramp of working out each body part once per week. I think there is a similar version of this in muscle and fitness but homemade is always better! each week one muscle group will be worked twice per week. putting some good strain on that muscle. than the following three weeks that muscle group will go back to once per week to prevent overtraining. arms will always be worked only once but you can adapt my program if you wish to work them twice over another muscle.
