"Results showed that there was a significant time effect for fat-free mass and the bench press, but fat mass and body weight did not change significantly."
This doesn't add up to me. If fat-free mass goes up, but body weight is unchanged, then fat mass must go down. Or if fat-free mass goes up but fat mass is unchanged, then body weight must go up.
So how can fat-free mass go up, but fass mass and bodyweight is unchanged? This doesn't make any sense to me.
