The biceps curl is a basic exercise that everybody is familiar with, but many lifters don't know how to do them as well as they think. These three tips will help you get the most gains from curls.
Mechanical tension is the main mechanism behind muscle hypertrophy (growth) and strength gains are joint-angle specific. So, maximizing mechanical tension throughout the entire range of your curl is essential to getting the most out of each rep. These three tips are meant to do exactly that.
You probably never thought about it, but most people can't produce as much force using two bilateral limbs to perform an exercise as they can if they perform the exercise with each limb individually and then add together the force of each side. It's called the bilateral deficit and you should take advantage of it to pack on some muscle.
