What are the benefits of leg extensions?
by
Leg extensions are a key exercise in strengthening the patellar ligament and quadriceps attachment for the knee. This exercise focuses on strengthening the quad alone and, therefore, strengthens key attachments for the knee joint at the same time.
The bottom line is that squats don’t work your rectus femoris. They will work your vastus lateralis (the sweep) at the middle and towards your knee, but not up towards your hip. For optimal rectus femoris development, and vastus lateralis growth towards the hip, opt for leg extensions.
Is leg extension good for growth?
Leg extensions were found to provide superior muscle growth in the rectus femoris compared to squat training. Vastus lateralis tended to grow more in the distal parts (25% and 50% of femur length) from squat training but grew more proximally (75% of femur length) from leg extensions.

How many leg extensions should I do per day?
Leg extensions tend to work best here. It’s up to you how many sets you do/need; however, 5 is usually a good amount. Start the first set off lightly, maybe 60% of your working weight for 10-12 reps. Increase this to 70% for the second set, 80% for the third, 90% for the fourth and 100% for the 5th.
To start, try between 8 and 12 reps for 3 sets. A good tip for choosing the right weight on this machine is to not use a weight that’s too heavy. Even if you cando the move with a higher weight, that doesn’t mean that you should in this case.
