The average Leg Extension weight for a male lifter is 212 lb (1RM). This makes you Intermediate on Strength Level and is a very impressive lift.

Rather than using a leg extension machine, you can do leg extensions using ankle weights or resistance bands. For a seated leg extension with ankle weights, start with 5-pound weights and progress only to 10-pound weights.

Look for at least a 250kg max weight limit and you should be set. It’s also worth noting that the leg extension and curl attachment will have its own individual weight limit too. If this spec is available, check it’s in the range you’ll be lifting.
