I'm shifting a lot of my pool work to treadmill work as it allows me to 'walk' every day as I'm now ordered to

So, today - 30min crutching on the treadmill..
i stopped by the gym on the way home and actually wrote down the weights..I kept my reps short to only be there for about an hour - and tried to add in my own PHAT version - throwing in a few reps of higher weight at the end..Some I could have gone higher, some were plenty high enough

It was interesting though - in my little PHAT version, I tried numbers higher than I normally even test and with some, i discovered that I could be doing such numbers for the normal reps (e.g. the seated leg press - i could have been doing at least 100 for the regular reps)
chest press -> 8*50lb 8*50lb 8*60lb
bicep -> 8*40 8*45 8*45
hip adductor -> 8*160 8*160 8*160 3*175
hip abductor -> 8*175 8*175 8*165
these numbers...baffle me...for the last few months, all i've done is one-legged biking and leg lifts...granted, i had a (oooo) 3lb cast on my foot, but...i keep thinking these machines must be broken, but then i see other people using them with *much* lower weights..beats me..but, can't say i mind the concept that my legs can do such..
back extension -> 8*100 8*100 8*100
torso twist -> 8*70 (ea side) 8*80 (ea) 8*80(ea) 3*100
leg lifts (L) -> 8 8 8
knee lifts -> 8
tricep pushdown -> 8*60 8*60 8*50 3*70
lateral -> 8*40 8*35 8*30 3*40 --i'm really weak on these
seated row -> 8*55 8*55 8*55 3*70
pulldown overhand-> 3*70 3*70 3*70 3*85 3*100
pulldown underhand -> 8*80 8*80 8*80 3*100
seated leg press -> 8*90 8*90 8*90 5*110
leg curl -> 8*40 8*45 8*50 3*65
leg extension -> 8*70 8*70 8*70 3*85
ab crunch -> 8*95 8*100 8*100 3*110
