How Cams Modify Resistance on Gym Machines - With Examples

Here are a few examples of cams and how they can impact the resistance on gym machines. The machines we looked at include: 0:00 Arsenal Strength Lateral Raise 1:25 Hammer Strength Abdominal Crunch 2:07 Hammer Strength Bicep Curl 3:44 Hammer Strength Pec and Rear Delt Fly 5:38 Hammer Strength Lying Leg Curl Key point - The cam might be showing a change in moment arms throughout a range but this does not always mean that the machine will offer a corresponding change in resistance. There are other factors to consider. Filmed at World Gym Castlereagh Street Sydney CBD.
