Started with traditional brosplit and ra n 3-4 cycles of stronglifts in my 2-3 years of training . Now I'm currently facing plateau from last 6 weeks. Plz advice on a good training program to increase my strength .Never followed anything other than stronglifts , now I'm being more motivated and dedicated towards increasing strength than ever. Read a alot about training methods like Madcow , Texas method etc. Any advice on what should I follow and which would be the best. Nutrition advice would definitely be a plus . Thank you.
