Not sure what you mean on the squats. It sounds like you are a new lifter, and this is your first program. If you do legs in one day that is probably okay. Not the best, but okay. Taking two major muscle groups and lifting them together is a bad idea unless you are getting a lot of help from some serious anabolics. Your body just cannot recover fast enough.
Try something like this:
Day 1: Back/Bi's
Day 2: Quads/calves
Day 3: Off
Day 4: Chest/Triceps
Day 5: Ams/calves
Day 6: Shoulders and abs
Day 7: Off
There are a lot of ways to break up the body. I have used one body part day six days a week with huge success. So did a number of great bodybuilders.
It is easy to remember and you have some fun short days like shoulders and Arms thrown in
To clarify on the squats: I don't have a squat rack, but I have a piece of equipment that I can rest the barbell on that is about the right starting height. I can get under the bar and perform the squat, but I don’t have a safety “catch” or a spotter, so I have to lift with less weight to be on the safe side. I can go up to about 250 lbs, so it’s not too bad.
So, yeah, I never really reach “failure” when I do squats, or even dead-lifts, which is maybe why I can do them on the same day. I realize that I won’t get as much of a benefit this way, but I have to be safe. I did my back/leg routine 2 days ago and I’m still feeling it, so that tells me that I am getting at least a little “something” from my workouts, right?
As for anabolics, I only use creatine and glutamine along with NO Xplode; pre-workout drink. I am, however, trying “Precision Engineered Perfect Storm” today. It has creatine, amino acids, carbs and insulin-spike. It’s new and I haven’t been able to find much info online about it, but it sounds like a helpful supplement (but how safe, I don’t know). Any recommendations on supplements?
