I've been with my Personal Trainer for 8 months now and we are working on reducing my overall body fat percentage and measurements. at the beginning we would do the weigh in before a training session and then we switched to doing it after a training session as it seems that my body fat % is LESS at the end of a session than at the beginning.
Today was my weigh in, and we went in before my session as the room was free. Everything was good but my body fat was at 25.7% We decided not to record that as it would have to be wrong because my weight came down as measurements down too. So we did a 30 min intensive workout and went back in to try the body fat. Second time round it came down to 24.2%. So in a matter of 30mins I lost 1.5% body fat?!! My trainer is a bit stumped on this one and said he will try it with some of his other clients.
Does anyone now why this would happen? I've tried googling it but have not found anything..
