Now, most 3-day splits I see are structured around each day having 1 main lift (DL/BP/Squat) and then following with 4 or 5 assistance exercises. Then, I read this from exrx.net The American College of Sports Medicine recommendations for resistance training exercise (summarized with authors notes in parenthesis) * Perform a minimum of 8 to 10 exercises that train the major muscle groups. 8-10? I usually do 5. Am I totally misinterpreting this, because from what I somewhat gathered, 8 to 10 could lead to over-training (or are just downright useless since the muscle is just getting hit and hit redundantly). Forgive me for my ignorance, but please help me out with this.
