I started my workout on squats, and just didn't feel it in me. failed at 8 reps (doing set of 20). Realized the bottle of hyperpump was in my pocket, and hadn't drank it. popped it right then, and went on with my workout. new PR on wide grip pulldowns. worked biceps a little higher weight today, they felt "snug" even 3 hours later. Was a nice pump on bis + tris today, didn't really get much on chest.
