When I started my weight loss journey a few years ago, I joined a gym. Unlike most people, I stuck with it.
When the gym added a room with workout videos, I spent most of my time in there. Hmmmm.....said I. I could do a lot of this at home....and save the monthly fee.
This started my adventure with on demand and youtube exercise. The best exercise for me is barefoot and low impact. Ellen Barrett and Jessica Smith have great routines. There is nothing frenetic about the workouts but you get cardio and strength training with no special equipment except for the occasional light dumbbell.
I still want to take Krav Maga but that is going to have to go on the back burner for now.
