You spend calories (energy) on exercises and therefore loose weigh (mass) in that process immediately. But that process also breaks protein molecules in your muscles and in heavier workloads it results in your body rebuilding those muscles with sort of muscle scars that will get bigger than the original muscles was and that will eventually lead to weight gain in longer time span. Or do you deny the existence of bodybuilding entirely?

All the radioactive ones maybe?
