Here is the routine that I am utilizing to tighten up my waist in 2007. It is very similar to my previous routines. The key for me is to keep a low volume of intense exercise. Everyone is different genetically, and some people can handle a higher volume of intense exercise than others. I have more of an ectomorph body frame, and I do well with only 2 days of intense activity per week.
For anyone taking a New Year's resolution to lose weight, I would encourage you to lean more towards lots of walking rather than lots of vigorous exercise. If a person bites off more than they can chew and burns out, it's easy to lose hope. It's better to underestimate the amount of intense exercise you can handle (you can always add more later). You only need a bit of intense exercise along with lots of walking to lose weight. Here's the routine:
Day 1 - "The Chase" - 20 minutes of intermittent running (stop-and-start); walk 40 minutes.
Days 2 and 3 - Walk 60 minutes.
Day 4 - "The Hunt" - intermittent running followed by weightlifting followed by immediate eating of meat; walk 30 minutes.
