Is it normal to feel pain during strength training?

Muscle fatigue - that burning sensation during the last few repetitions - is normal. Sharp pain, joint pain, or pain that worsens as you continue is not. Stop the exercise if you feel sharp or localised pain. Mild discomfort is training; pain is a warning signal that something needs adjusting, whether that is your form, the weight, or the exercise selection.

How do I know if I am progressing too fast?

Signs of progressing too quickly include persistent soreness lasting more than 72 hours, joint pain (not muscle ache), declining performance across sessions, and dreading your workouts. If you notice these signs, reduce your weights or volume by 10-20% and progress more slowly. Your connective tissue needs time to catch up with your muscles.

Should I train through muscle soreness?

Mild muscle soreness (DOMS) is generally fine to train through, particularly if you warm up thoroughly and the soreness eases as you move. However, if soreness is severe or has not improved after 72 hours, take an additional rest day. Training through significant soreness increases injury risk and impairs performance.
