I want to know what muscle groups are good to work on the same day. Usually I work my chest and triís, back and arms/biceps, core just about everyday and legs on Sundayís. I always start with 25-30 minutes on the eliptical machine and then go into my workout for the day. I typically hit the gym Monday, Tuesday, Friday, Sunday and ride on Wednesday and Thursday, occasionally skipping the gym on Saturday and or Sunday. By the way, my goal for the gym is overall fitness, burning some fat for the up coming season and just overall fitness.
