Squatting is one of the best exercises for the body, and while I love deadlift, both is much more effective than only one.
Both? I am a 47 yo male, overweight and (frankly) in pretty bad shape, doing a full body routine 3x / week. I am a little afraid of deadlifting 3x / week, let alone deadlifting plus squatting. Won't that be a little much? I'm especially wary of re-injuring my lower back...
Okay sorry, I didn't catch all of that my first time through the thread. You're right, I wasn't intentionally
suggesting squatting and d'lifting 3x a week. That's insane, and counterproductive. Also, I failed to see that you're worried about reinjuring your back. However, I feel squatting and d'lifting on the same day is the way to go, when you do either. So maybe squat 2x a week, and d'lift 2x a week, and make sure one of those three workouts a week contains both. Plus, I don't think just having them be together will increase risk of injury, so long as you're doing weights with each of them that you can properly handle (with good form). Hopefully this clarifying post makes my earlier one not seem insane.
