For me it varies. Once upon a time I was a regular @ the gym, bought a treadmill several months back so now rarely go to the gym. I like to do a 300 Calorie workout that takes 30 minutes. Today I’m planning on going to the beach to play with the sharks(jk). Boogy boarding with fins on is the most fun way for me to burn Calories. A couple of hours of wave riding and I think I’m good for the day as far as exercise goes.
