hey u all...ive noticed that the past two weeks...ive been so tired...ive gone to bed like an hour and a half earlier than usually and i take more naps...and during school im very tired...i hear sometimes this symptom could be the cause of overtraining; however, i find my workout plan wonderful for me. Ive noticed increasing weight and strength on all my muscle groups, and ive gotten to look better...but im still tired...maybe its just cause im a teen. I work out each muscle group twie a week...giving each group 72 hours of rest...i dont think i need to start only doin one muscle group a week because i dont train till failure on lifting days...im not a totally serious bb.
