THIS^^^^^^^^^, forget about the weight on the bar, your muscles do not know numbers, the only thing that does is your brain. You WILL NOT build big muscles by lifting big weight, you must build big muscle to lift big weight!! How do we do that? We use an appropriate weight that we can lift for sets of 8-12 with perfect form, and keep tension on the muscle the whole time to induce hypertrophy. Its all about time under tension NOT how much weight your lifting.
Be smart, why bench 225 when you can make 135 feel like 225 and have it do the same job, and avoid any injury
At a certain point your joints and other muscle groups take over the load and now your hardly even work the intended muscle group.
Fuck what the numbers say on the bar, get that outta your head.
