First, the confessional - I'm really bad at sticking to a fixed rotation.
Having said that, I did a WHFN rotation several years ago and I admit to being pleasantly surprised with the results. I'm not an apple, but I am in my 50's and have started having that tendency to hold to a little extra around the mid-section. I like the fact these work-outs are typically paced so that you can up your weights as your fitness level improves and can also use bigger moves and/or impact to increase the cardio intensity.
And you're right......watching the fork-to-mouth piece makes a big difference, also. The good news - we have a lot of great fresh produce to enjoy this time of year.
Good luck!
