You shouldn't be puking. There is some element that is either present or missing. You could be pushing yourself too hard, you could be eating too much immediately prior, it could be some unknown. But you do not want to puke after a workout, it is your body's responding to you pushing it past it's limits.
Yes i like push my self every workout no matter what it be...but i only ever get this with my leg workout

At first its all my body thats doing it but towards the end i have to use my brain...its crazy :yelrotflmao: hard to explain i guess...and yeah i have done many leg workouts and as i sead only happened twice but it was the exact same sickness the way it came on and i only just got to leg curls every time.
