Are You Training Hard Enough?
When you’re training with weights, your goal should be to increase your strength. When you increase your strength you’re going to be gaining more muscle.
Every time you come into the gym your goal should be to add reps or to add weight.
Weights for the big compound exercises like squats, bench press, bent over row, deadlifts etc. should be going up week by week. If you benched 135 last week, your goal this week should be to bench 140 pounds the same amount of reps.
