Bench Presses
See, I didn't keep you in suspense waiting for this one! When I was 19 or 20 and training back at the Gold's Gym in Worcester, MA, the bench press was a very big deal. We had a few guys who put up 500 pounds or more on a regular basis. One of them was Frank McCullen, who only weighed 165 pounds! So I saw that and figured I had better be able to do at least that much, since I had a good 70 pounds on him. The best I ever did on the flat bench was 550 for 2 reps. These days, due to the fact that the risks far outweigh any possible benefits to my chest, you won't even catch me under a flat barbell bench press (only a Smith machine for that movement), and you certainly won't see me doing 2 reps of anything. Back then bodybuilding was not my career yet, so worrying about injuries rarely if ever even crossed my mind. Now, it's always at least in the back of my mind at every workout.
-----------------------------
Incline Barbell Presses
My best incline was 405 for 6-8 reps. Nothing spectacular, but it wasn't bad. This is an exercise I will still do, unlike the flat bench.
-----------------------------
Dumbbell Presses
I once pressed a pair of 200s for 2 reps during a photo shoot three days after I turned pro at the 1996 Nationals, at Club MET-Rx in Costa Mesa, CA. I probably wouldn't have even tried them except that Chris told me Greg Kovacs had just done them at his recent shoot. I pressed 160s to 180s all the time back in the late ‘90s.
-------------------------------
Squats
My legs were really strong when I was in my late teens, even though I hadn't been training very long. At 19 I remember squatting with close to 700 pounds for a couple reps, and the reps were always ass-to-the-floor. Back then my legs totally overpowered everything else. I used to squat 500 for 10 reps like it was nothing. Heavy squats have always made my lower back tighter than any other exercise.
----------------------------
Front Squats
The most I ever did on front squats was 455 for 6-8 reps. That's one exercise I never maxed-out on, because I never saw the point. How often does anyone ever ask you how much you can front squat, anyway?
---------------------------
Deadlifts
I've done six plates a side, or 585, off the floor for 3 reps. I did it back in 2005 at the Gold's Gym on Sahara and Decatur in Las Vegas. I still do deads. Nothing pumps my back up the way they do. I've also done my share of rack deadlifts, and the most I ever used was seven plates a side, 675 pounds, for a few reps— somewhere between 3-6. Forgive me if I don't always remember the exact number of reps I did.
----------------------------
Overhead Barbell Presses
Back at the Gold's in Worcester in the early-to mid-1990s, behind-neck barbell presses were a very popular lift, and somehow everybody went up to 405 on it. Obviously that meant that the spotters were often doing a pretty heavy upright row! I recall being able to do a few good reps without much help at all. In 2006 and 2007, my main pressing movement for shoulders was the standing barbell press. I can say for sure that I did those reps on my own! I went up to 315 on standing presses. That's one exercise that involves a lot of technique. If you get away from it for a while and come back to it, you find you can't handle anywhere near as much weight.
--------------------------
Seated Dumbbell Presses
I have done the 160s for 8-10 reps, but I don't feel the need to go quite that heavy anymore. I still go up to the 140s. And I should note that I will have someone put them on my legs, but I like to kick them up into the start position by myself. I just feel like I have better balance with them that way, as opposed to having them handed to me at shoulder level.
-------------------------------
Close-Grip Bench Presses
I have done 405 for sets of 8-10 in the past, but this is an exercise I kicked to the curb after finally realizing it was not a safe movement for me. So however much you use on your close-grips, it's more than a four-time Mr. Olympia.
