I just got back from the gym, a good session from 9:30 to 11. After a few days off, I did a full lower body workout. It really got me (laughs), though my strength dipped on some parts.
Then came cardio: the stair climber. Ten minutes in, I almost passed out. My heart rate stayed in Zone 3, but the exhaustion was intense after legs. I'd planned for twenty minutes, but ten was my limit.
I got off the machine immediately and lay down by the fan, almost blacking out. I'm resting now, stretched out. Still haven't showered, and I'm starting to get hungry. I'll head to the shower soon.
