More weight than I thought

I checked the unloaded weight of the squat machine I have been using. It says 52lbs.

I now know that my squats have been 1 set each of 5 reps X 142, 232, 282.   Not bad for a 140 lb guy.

Also bench press with olympic bar is 1 x 135, 155, 175

The low rep method is working well for me...

I sometimes add a set of Pullups - 10 reps, and assorted other things like dumbbell shrugs with 45 each, or tricep presses after the bench press routine. Keeps it interesting.
