I try to play Dance Dance Revolution for at least 45 minutes every day. It's the only indoor cardio that I enjoy that really gets my heart pounding.
I've done Occam's protocol for about a month or so with good results. The goal was to add muscle to my upper body since spaghetti arms don't really match with the calves-of-steel I got from several years of playing DDR.
I've decided to switch over to a strength building program now though because if I add any more bulk I've going to have a difficult time finding women's clothes that fit me. I'm quite short with broad shoulders and narrow hips and I seem to add muscle easily.
I found the Effortless SuperHuman chapter to be a little lacking so I got these two books from Pavel Tsatsouline (mentioned in the chapter).http://www.amazon.com/Kettlebell-Strength-Secret-Soviet-Supermen/dp/0938045695/ref=sr_1_1?ie=UTF8&qid=1306820141&sr=8-1http://www.amazon.com/Power-People-Strength-Training-American/dp/0938045199/ref=sr_1_7?ie=UTF8&qid=1306820141&sr=8-7
These are both minimalist programs similar to Occam's Protocol but with an emphasis on maximizing functional strength. If you like how Tim writes, you will probably like Pavel - he gives you plenty of geek-friendly theory as well as a simple, practical workout plan.
The strength workouts do not require adding carbs and they don't tend to cause muscle soreness. You don't train to failure either so it's safer and you can work out a lot more frequently.
I've been easing into a combination of the kettlebell and barbell workouts for about a week now and I feel totally awesome. I did buy a light 20 pound kettlebell so I could learn the advanced kettlebell moves without hurting myself, but I still use the t-handle for the kettlebell swing. I've already learned a couple cool tricks that has me opening jars I couldn't get before and carrying my husband around the house.
