Why am I doing this? Because I'd like to see if I can control my heart rate though exercise, NOT diet, and not medicine, in part because my diet is actually really good. And, clearly, if it's just exercise that's making my heart so weak and flabby, then I want to make sure it's getting what it needs naturally BEFORE I try medicine.
Anyway, I made it three times easily last week and maybe even four (I can't remember), but I did also make it to Pilates on Friday for the first time in three weeks and it kicked my butt so badly that I was still feeling it (on the outsides of my thighs) on SUNDAY. Still, that means it must have been good for me - and as long as I'm feeling it in my muscles and not in my back, I think I'm doing alright.
