Simple Workouts
I have to give that woman in the gym 10 out of 10 for effort. The underlying principle of her workout was perfect, she was doing short bursts of intense activity. The thing that beguiled me however were the wide array of exercises she was doing. Skipping, jumping side to side over some hurdle, lunges with her arms flapping in the air. Was it all necessary?
Keep it simple, honey.
