I've been gaining great strength in the last few months since bulking up (these numbers taking off top of my head: Squats approx 50kg, Deads approx 40kg+ and Bench about 30kg) and still have till January to put on some more muscle bulk. However, I was wondering should I stop trying to smash my records nearly every 2 weeks with my strength lifts of 5-6 reps usually and focus on a more muscle build up hypertrophy at 8-12 reps of 65-85% of my 1RM? I'm just wondering really which is better to build muscle in my last 10 weeks, opinions greatly appreciated. I just want to gain optimal muscle mass (assuming my nutrition diet is correct, which I'm very sure it is), and aren't most of us here to do that?
My big bad lifts like the Squats, Deadlifts, T-Bars, Bench Presses etc etc I could maybe keep trying to put as much strength into them as possible and go to a more mass builder (8-12 reps) on other exercises? Or you think I should bring exercises like those mentioned to 8-12 reps mostly if I can and maybe set aside a set for heavy lifts? All in all, those big lifts will be heavy, but not as heavy as I'm doing now, if that makes sense?
Just want advice on the best approach for optimal muscle mass gains in the last 10ish weeks of my bulking phase. Thank you guys.
