That was the helpful advice offered to me by my (smokin' hot) personal trainer a four years ago.
Was that bit of wisdom worth the $100 an hour I was paying him?
Looking up his shorts as he stood above me making me do crunches was worth at most $40 an hour. (Boxer briefs, navy.) I would have gladly paid him the remaining $60 just to not make me see stars and nearly puke from over-exertion.
Since that day my weight has been down, up, down, up, down, and currently UP. I'm upset with myself, yet I'm doing nothing to make things better.
Just put down the fork. Easy for a 25 year old rugby player/personal trainer with 3% body fat to say.
