Jack has been an amazing trainer for me and my boyfriend. He really cares about his clients and builds a relationship with them. I really like his follow ups. He shows me how to integrate exercise, fitness and improve my diet and apply these to my life without having to make wholesale changes. He is able to customize to my needs and personal limitations. I have had immediate benefits. Within two weeks, my boyfriend said "WOW! Your waist is so much reduced! I will highly recommend Jack to anyone who is serious about improving their personal fitness or impressing his/her counterpart.
