Use perfect form when doing compound exercises for arms. Otherwise, you’ll hit other muscles in your body.
Practice perfect form at all times.
You should feel the biceps and triceps contract as you train them.
Your muscles grow based on how much they are being stressed.
They don’t “feel” the amount of weight you’re lifting. Hardgainers should master proper form before they start lifting heavy loads
