How to Build a Leg Extension and Leg Curl Machine | Home Gym Build

in this video I turned an old squat rack that we picked up from the trash into a leg extension and leg curl combo machine. I've been wanting to build something like this since before I knew how to weld (when I was like 13) but I never really got around to it. Now about 80% of my home gym is homemade (except for the dumbbells of course lol)
this is a video on how to make a homemade leg extension machine. it's a higher skill level project but definitely possible. in the future I would like to make a DIY leg extension leg curl machine and a homemade DIY leg press machine. another cool project that i would like to get to one day is a homemade DIY squat rack. In the next home gym builds I will be building a home made DIY dip station for my squat rack, catch you in the next one ;)
If you're interested in other things i've built, check out this dumbbell rack I built when I was 16

or this DIY swiss bar I built when I was 15

or even this DIY lat pulldown machine I built last year

    Here is a link to the blueprint I used to build this... This is a basic blueprint because most of the work I did was figured out throughout the process of building this machine drive.google.com/file/d/1R0bbKJN43wafZCSZFdOJ18T19X1-HVKK/view?usp=sharing
