I have been training with Sammy and Travis for the last 2 years.
We do group training in a group of 3-4 work mates three times a week: one full body session, one lower body session and one upper body session. My goal wasn't really to loose weight, but to become stronger, fitter and to tone my body. Sammy and Travis are doing a great job and I can feel a big difference in my strength and my endurance. I find it really good to train with a PT instead of doing it on your own at the Gym, because you get a diverse program of exercises each session - in accordance with your strength and abilities, not too easy, not too hard, but a good challenge. I love the comments from Sammy and Travis. They help a lot, to do the exercises the right way and to get most out of them. I feel after the sessions always somehow good and happier :-).
