Sheps is right plenty of cardio work- skipping, running and any other exercise you can do for 45 minutes. Speed sessions mixed in gives variation and helps to raise your metabolism.

It's good to sweat during workouts through hard work and intensity. Don't bother about wearing loads of clothes during a workout. You'll replace the sweat you lose when you have a drink - so don't dehydrate yourself unnecessarily.

Good luck and train hard.
