I do one hour Krav-Maga classes on Monday & Wednesday evenings. This class kicks my butt!! We start with some stretching, then it's 30 minutes of intense calisthenics & sprinting. For example, run in place for 30 seconds, then do 30 seconds of pushups then do 30 more seconds running in place then 30 seconds of jumping jacks, running, then crunches, etc. We do this like boxing rounds; 3 minutes of exercise with a 1 minute break between rounds.
Then we move on to the actual sparring and training portion of the class. This class wipes me out but I feel great for doing it! Learning self defense isn't bad either.
To try and get myself into better shape for this class I ride my stationary bike on Tuesdays, Thursdays and possibly Sundays as well. Friday nights I do some pushups & crunches, but I plan on hitting the gym instead on Friday nights and doing some light weight training at home on Saturdays as well.
Since I've enrolled in the Krav-Maga classes for 7 months I
have to go. There's no way out of it.

The other stuff I'm doing to try and get into better shape and try to reduce my gut size and lower the strain on the bathroom scale.
