just general excersise everyone thinks i just drink and smoke but you would be wrong, i go kick boxing twice a week and train but i also practice at least an hour a day and if im working im moving all the time and then riding on top, just eat healthy keep your body hydrated and dont eat crap like crisps and chocolate all the time, every night i do 50 sit ups n bit of training and it helps especially if you been on the beer haha
