First two weeks down and I feel better. Unfortunately I tore/pulled my left hamstring (had cramping the first night and fought through which did more harm than good) so my workouts have been limited to upper body for the most part. That being said I'm still getting VERY good workouts. It's kind of mind boggling because back when I did cardio/lifted a injured hammy would have meant your workouts were VERY limited. Only a few movements and it would be difficult to get a good cardio/lift workout. I've been able to observe the fundamentals class and then when they put them into action the trainers came up with a workout I could do on the fly that was both challenging and fulfilling. I ran out of breath and had to push through just like the other people in the class who had use of their lower body. Naturally I'm bummed I can't do the lower body workouts but at the same time I really felt like I've got good workouts even though my knowledge of movements to this point are very basic. I can only imagine that once I've been doing this for a while and learn the more advanced movements that I could get even more out of an all upper body workout. That being said, my hamstring is starting to feel better and I'm chomping at the bit to get going again. I suck at running and really need to work on that so getting this sucker back to service will go a long ways in my overall advancement and fitness.
