When I'm traveling, I really love p90x. I have it ripped to hard drive on my netbook. Gives me no excuse for not working out.
At home I lift 5 days a week and do different types of cardio - cycling, running, rowing, and hiking.
My lifting routine changes every so often, but I'm a big believer in progression. I do two week "cycles" of 10 rep and 5 rep sets. I set a goal for the end of the two weeks and then work backwards, so every workout adds a little more weight.
My focus is on the big compound exercises with auxiliary exercises added in where appropriate
Day 1 - squat
Day 2 - bench
Day 3 - deadlift
Day 4 - standing overhead press
Day 5 - power clean
My physiology makes me well suited to deadlift and terrible at bench. Long arms and short legs. I like to set short term and long term goals. Right now, my main goal is to deadlift 500 lbs for my 33rd birthday which is 9 months away. I'm chipping away at it and I'm on track to meet my goal.
I wouldn't be able to do what I do without good instruction. I feel really lucky to have found an excellent trainer who is a competitive powerlifter with tons of knowledge. Form and technique is so important. I often cringe at what I see people doing in the gym.
I love lifting. It keeps me sane. I'm a grouchy SOB if I miss more than a few days. I only wish I had started sooner. I didn't get serious about until my late 20s.
