Which was then followed by the "triangle of death". Lunges with 15lb, cycled with stepups with 15lb, cycled with ball squats with 70lb. By the end of that, I was pouring sweat, I was stitching up my sides all the way thru my neck, my hands and forarms were cramping, and my peripheral vision was gone.
Since the loss of my gym bag, I had to wear my ordinary black boots in the gym. I think that they made the balance for the lunges and for the standing calves easier. At least, on the calves I was able to cook my legs without pulling the soles of my feet, which is the usual limiting factor.
Speaking of which, I set a new rep times weight record for calves, as well.
Calves are weird. Once the "burn" sets in, it's going to last 30 agonizing seconds, whether I stop or keep going. So I just keep going, and then hop off, and grit my teeth and wait for the pain to fade. No other muscle feels like that.
