Is it better to hit 1 or 2 main muscle groups a day, or shoud I mix it up a little bit more (Do a little bit of each every workout day.) I'm attempting to put together my first routine by myself: Day1 Arms/Delts/Upper Chest Seated curl Tri extension/skull crusher Bench Press Dumbell Fly Behind neck press Reverse Curl Day2 Lower abdomen/Back Bent over row/lying row (barbell) Shrug Chin ups/Pull ups Push ups/Sit ups 8 minute abs ( ) Day3 Legs/Compound movements Squats Deadlifts Calf raises I'm obviously open to any advice. I'm not entirely sure what I'm doing so any help is appreciated. My main goal is to change body composition and hopefully maintain my weight (6'5" 225 lbs) if not lose a little. I'll figure out my sets and reps throughout this week to see what works best.
