Hey guys,
Im just curious about the difference in resistance between a short barbell arm/bicep curl and a arm curl using a pulley (the one where you can also change the height)
I could do 70lbs on the free weight and feel a good pump but for some reason i can do 145lbs with the one on the pulley same reps and sets.
So i wanted to know if anyone knew the formula to calculate the difference in resistance between weights.
For example Leg Curl vs Squat resistance is (lbs x sin 45deg)
thanks for the input
