Dexter's classes have been absolutely great for me.  After years of poor diet and lack of exercise, I felt sluggish and lacked energy.   A lack of energy was affecting my ability to keep up with super long days (6am-11pm) at the office and school.  I wanted something that would allow for a physiological change in the way my body is able to use energy as well as the psychological and mental benefits of exercise which include the ability to cope with stress and maintain focus, amongst others.  After consulting with co-workers, several of them recommended Dexter.  I was told that he will allow me to achieve results quickly and that I would have fun getting there. 
I joined his classes weighing in at 220lbs, and am now 200lbs.  I think a major benefit of his class is that it motivates you to live an active lifestyle outside the class.  After a few sessions you will most likely start experimenting with other exercises, as well as adjust your nutrition habits accordingly.

In the class, you can't use any excuses with Dexter, he will push you regardless.  Since attending his classes,I feel more focused and more energetic.  I have the same energy in the evening as I do in the mornings now.

In the end, I have gained physical and psychological benefits but also my self-esteem has improved.  With Dexter's help, you will be surprised at how much you can accomplish, so it's only natural that you will wonder what other areas of your life are being limited by similar beliefs.  I would have never thought I could learn how to swim late in life, start my own business or break out of my shell.  Looking at my accomplishments since training with Dexter, I no longer fear the unknown and limit myself in terms of capability (it's surprising the things you can do when you really feel good).  Without any hesitation, I can promise you that Dexter's regular training will prove to be a catalyst in some area of your life.
