What's the routine look like? As Brute said, you're probably fine so long as you aren't doing too much volume and you give your body time to recover in the grand scheme of things. It's not uncommon for guys to do several squat, deadlift, or bench variations in one day-that's not the problem. The problem is when you do those several variations, several times a week, several times a month, etc., you can overtrain.
Note: There is a huge difference between overtraining and overreaching!
