FAQ:

Q: What are the benefits of a leg curl machine?

A: The main benefit of leg curls is to focus and isolate the hamstrings. Our hamstrings are likely lacking in size and strength compared to our quads. This is because it is generally tougher to train our hamstrings through knee flexion in other compound movements. This is where machine leg curls/hamstring curls come in.

Q: What muscles are used in leg curl?

A: The calf muscles are made of two muscles, the gastrocnemius and the soleus. But the one that is used the most during a leg curl is the gastrocnemius, which is most superficial.

Q: What is the best exercise equipment for the legs?

A: Machines are great at targeting and isolating specific muscles. The best free weight exercises for the legs are dumbbell squats, dumbbell lunges and dumbbell calf raises. Some machines that provide the best leg workout are the leg press, leg curl and stair stepper machines.

Q: What are alternative exercises for leg extensions?

A: In fact, a study published in March 2012 by the Journal of Orthopaedic & Sports Physical Therapy explains that weight-bearing exercises, such as squats, lunges and step ups, put less stress on knee ligaments than open-chain exercises, including leg extensions. Squats are a great alternative to leg extensions.
