That's awesome Huy! Impressive numbers for sure.
I'm with Charlie, a little bit heavier
and not anywhere close.
Charlie, for my cardio I have been doing mostly erg rowers with stair steppers and maybe once a week on the treadmill.
My preference is the rower, I'm not threatening any Ivy League scholarship, but it kicks my ass. I feel like it gives me a good whole body workout which none of the other cardio machines seem to do.
