Do you ever get sore? Do your legs get stiff?
When this happens, your legs lose definition. Reason being: your body is retaining water in the muscles to help them recover. A person can easily hold 3-6 lbs. of water, depending on the soreness and size of the muscles. A good rule of thumb i to not weigh yourself the day after working legs! The best time to check your weight is once a week, on the day after your rest day. This will ensure you keep focused on your diet and do not cheat on your rest day.
