I've been strength training for the past 4-5 years. I like my gym and vary up my routine, but I have been doing more and more research about Crossfit. I like the concept, a lot of functional movements and high intensity exercises. However, I worry about whether these exercises are possibly too intense and could gradually wear down your body. For instance, doing some exercises like deadlifts to muscle failure appears to be dangerous as it becomes very difficult to keep your form. These concerns and research next led me to Gym Jones. Similar concept, but they don't have a "one size fits all" approach, and I don't have to find a box to workout in. Instead, they provide the workout routine and I find the time and location to do it. They also have dozens of customized workouts depending on your fitness goals. This seems to make more sense to me, but it's quite a commitment ($500 commitment for the year) to gain access to Gym Jones workout routines. Is anyone familiar with these two approaches and how they differ? Any thoughts, comments and concerns are appreciated. Also, FYI - I'm starting to really focus on a Spartan race in September, so I would probably adopt one of these two approaches after the race. Right now, I'm all about race training. Thanks for the help. Kenny
