Been lifting for almost 10 months, 2,5/3 hours a day. I only gained about 4 kg (i’m 63 kg, 1,72 m), but a very low body fat, and my body changed in a way that everyone compliments me for it. But, even that me meals are ok, i’m suplementing with whey, i can seen to go further for the last months, a lot of people been telling me that it is due to the long time that I lift, and I should spend much less time of the day doing it to increase results. Is it true? Am i doing it wrong?
