Thanks, guys! I'm just doing my best to keep up with everyone else here.
Of course, it wasn't just bravado behind last workout's push; after the squats, i had to wait for my husband to finish with the barbell, so i had some time to think and analyze my knee. Also, i've felt like i could up the weight for some time, cause it feels like i've been squatting 100 for the longest time. I think it was actually the volume that was holding me back. Dan had the right idea; even if i felt like i could do more, i knew i'd have 4 more sets ahead of me, so i was holding back. Changing it from 5 sets to 3 made it easier to give those lifts everything i got.
So today was a cardio day, and i spent it on a treadmill. I timed it for exactly 30 minutes, using the incline like before. I tried to keep my heart rate between 130 bpm and 160, though at times it jumped to like 180! I should probably look up whether this is a healthy range, lol.
Anyway, not much else remarkable about today. I picked up some honey so now i have some quick sugars for post workout.

Ended up at 1419 calories and 144g protein.
