Anyone ever work so hard on an exercise that it takes a lot longer than 2-3 minutes to recover? This only happens to me on squats. It's pretty much like my body overheats and can't settle down. I get really hot and start sweatin like crazy, sometimes get nauseated, and my heart rate takes about 3-4 minutes to normalize. Is this normal? Should I just not do so many reps on my squats? I'm open to ideas...see below for my squat schedule.
