On my last cutter I took up jogging, I got to where I could do a 10K no sweat, run for an hour on the treadmill and want to keep going. I lost a lot of weight, but a lot of muscle too. I've heard that 45 minute uphill walks are ideal for dropping fat w/out destroying all of that hard earned muscle.
What do you guys usually do to trim up w/out getting sucked up?
