Brad goes through how to do leg extensions with correct form on the Powertec Multi System. You will notice that he does not use a lot of weight in this demonstration but goes to failure. If you are doing this exercise properly and effectively isolating the quads you will not need a lot of weight.

Personally I was not a big fan of leg extensions until I recently started getting into specific bodybuilding training. One of the reasons why was because I used to get a lot knee pain. Like a lot of blokes I was too focussed on lifting more weight rather than focussing on isolating the muscle. Yes I was lifting a lot of weight but I was not lifting it all with my quads and the end result I was just stressing the knee joint.

Matt and I only do 25kgs for 3 sets of 30 but with perfect form. I get nil pain in the knee and my quads are screaming at the end. We probably won’t go up in weight in the future but rather slow the reps down even further. It is the perfect warm up for some squats.

You can also use the technique explained in the video for leg extensions on the Powertec Leverage Gym and the Powertec Leg Lift Attachment which can be used on the Powertec Multi Press, Powertec Olympic Narrow Bench, Powertec Shape System and Powertec Utility Bench.
