Going to disagree with you. 5 lbs per week maybe a lot but totally obtainable. Need to limit my meals to around 2k calories per day. And work out hour and half. I usually do that plus an hr or two training mma. So the burn is definetly there. I just need to prepare well. That's what kills me when I don't have food ready.
Just got back from gym and from cardio did 800 calories on elliptical, lifted for 35 minutes and then did ten minutes of sprints 20 on 40 off.
Other note research vibrams I know their was a class action suit about them couple years ago because they faked advertise the support.
