I have worked very close with iWorkout, Inc and the founder Eduardo Guernica. and I can tell you this is one of the best personal training experience Ive ever had! not only you get a great workout of them, but all the information and knowledge from the dietitians and nutritionists involved. you feel as committed to your diet plan as you as with your health and life in general, because they make you see the importance and understand the science behind everything you do!
