Cycling and swimming are perfect ways to build muscle and burn a lot of calories. See if you can find any mountain bike trails near you and get a mountain bike. Or go roads with some hills. Switching up your speed and effort works better then going at a constant rate.
For inside and cold winters turn yourself into a ddr master. Workout mode on expert with 150 bpm songs can burn 500 calories in 30 minutes. Equivalent to 90 seconds of sprinting and 15 sec break to load the next song.
