lean back. and do lateral pulldowns instead if you can't support your own body weight, you're probably cheating too much to get a good lat workout. try barbell rows or bent over t-bar rows or cable rows as well. *****.
...also don't use your thumb to grip the bar for pull-ups. Use the monkey grip (fingers all on same side of bar). I was reading one SEAL training book that mentioned this important point. Your grip will last longer and you can do more reps.
I'll second this opinion. I've just started this type of interval training (Called High Intensity Interval Training [HIIT]) and it is working. I feel much faster improvements in my running already.

The tabatta exercises are the core of my training. I find it to be the most funtional exercises for translating physical workouts into the type of strength and energy you need for fighting.
I recommend to anyone who is interested to spend sometime at Crossfit.com - you'll find tons of articles and forum posts on this.
