I also vary this and do singles too at 65 or so per leg until I’m “spent.” It’s nice to isolate each leg and see where your strength is. Most people have a dominant side.
EXERCISES: Leg Extensions
I know most of you know this machine, but I also wanted my blog to be for beginners to learn and some of you are still intimidated by the weight room. This is one of my favorite quad exercises and I like to wait until the end of my workout so I can work my quads to failure. (It’s better to fail on the leg extension than a barbell squat! ) I have been kickin’ it w/ my leg extensions lately pushing 150 – 175.
