So what really makes this program EXTREME? Well, 2 things. The first, is there is a countdown to competition eating plan. It is VERY rigorous, with way fewer food options. Still a lot of food, just fewer options. The second thing that makes this program EXTREME, is the intensity of the workouts. If today was ANY indication, I am in for some serious sweating and hard core results from the workouts over the next 3 weeks!! Today was Plyo Fix Extreme, and it was TOUGH!! I modified 90% of the program - mostly because Plyo involves a lot of jumping, and my ankles don't tolerate that so well. Still, I was working hard. In fact, I REALLY, REALLY, wanted to stop and rest, but I kept pushing through. My legs felt like jello afterwards, and going up and down stairs has been a challenge all day. lol!
