Q. Is using a biceps curl machine an effective way to develop large arms?

Just using bicep curl machines will only help develop the muscles on the front of the upper arms also called biceps. However there are other muscle groups also in the arm that need to be flexed to develop a stronger pair of arms. Therefore just by doing a bicep curl machine one cannot hope to get large arms. Along with this one must not neglect floor exercises to achieve a fit body. It is very important to do warm-ups along with push up chin planks and sit-ups to ensure that all the muscle groups of the body are exercised.
