In November of 2012, a friend talked me into getting a Groupon for Pure Fitness Training. Their boot camp classes are a high intensity circuit training workout that really works for any level of fitness experience because you can go at your own pace. I was very impressed with the type of training. So when they had a "Body Transformation" contest in February of 2013 I was in and have not looked back since (except to be amazed by my progress).
There are many things Pure does that are great. One of the things that I really like, is that the trainers don't just say go/stop. They walk around, look at your form, and do on the spot corrections to make sure you are learning proper form. They also provide modified exercises for your fitness level or if you have an injury. The trainers credentials make them stand out among other local fitness places that I have looked into online. At most local bootcamp style gyms, the trainers are only certified in "Group Training". I feel a person that has been through school studying how the body works and body mechanics probably has a better understanding on form and preventing injury.
One of the things that really has allowed me to continue to strive to keep working hard is they have an ultrasound machine to measure body fat percentage. I can keep track of my progress and set incremental goals. For example, I started out at 23% body fat (about 250 lbs) and now, I am around 12-15% body fat at about 200 lbs. Without being able to track that, I would be relying on a scale which does not show you how much muscle you put on versus fat you have lost.
