Today in the gym I finished up on my leg workout ahead of time and thought that it couldn't hurt to throw in some mild cardio........NEVER DO CARDIO RIGHT AFTER A LEG WORKOUT. I only had the treadmill set to 6.0 incline @ 6.5mph, I had to stop at .36 miles because I felt like I was going to throw up at any second. Came home,20 minutes later I felt worse and it hurt to try and eat. 1 hour later after burping a whole bunch and taking a nap I feel much better but I'm never running right after a leg workout again! Just aheads up to everyone else because I wouldn't want anyone else to expierence the same thing.
