I've been training for around a year but i have never been able to increase much poundage on dumbbell curls, even with HST. I’m alright with the rest of the bodyparts and exercises, but bicep curls just dampens my mood everytime I fail to improve on it. The only improvements I made on biceps training is only on cambered bars, but I have heard that doing bicep curls on cambered bars don’t really target the biceps due to the wrists positioning. I’m more interested in improving on incline curls and hammers. Is there anyway I can fix my problem or do I need to be more patient and stick with the current weight for a couple of cycles before increasing the poundage?
