What is a kneeling leg curl machine?

A kneeling leg curl machine isolates the hamstring muscles. It allows the user to strengthen them and increase their flexibility. However, the hamstring muscles are not the only ones that are benefited from kneeling leg curls. The machines also help work the muscles in the buttocks, thighs, and shins. This helps the users with their balance and stamina. 

There are different variations for the exercise along with variations in the machine design depending upon the type of exercise being carried out. For further information regarding how a leg curl machine is operated, please refer to the following video:

How does a trainer use a kneeling leg curl machine?

  • The user places their knee onto the knee rest and places the other leg on the ground with the ankles behind the pad. They brace themselves on the handles of the machine and lift their leg towards their buttocks.
  • The rest of the body must remain stationary while performing the exercise. The reps must be repeated for both legs.

What is the difference between kneeling leg curl machine and seated leg curl machine?

The difference is in their use. The process of using a seated leg curl machine is listed below:

  • The user places the back of their ankles on top of the pads.
  •  Bends their legs at the knees.
  • Lowers their feet as they pull their feet back underneath them.

They have a padded bar on top of the legs to prevent users from raising their legs while executing the leg curl.

What is the difference between Kneeling leg curl machine and standing leg curl machine? 

The difference between these two machines is how they are used for exercise. In a standing leg curl machine, user have to do the following steps:

  • The non-dominant leg should be worked before the dominant one and reps should be adjusted for the other leg.

  • Raises their legs towards their buttocks.

The users must be careful not to raise their hips as that could lead to lower back stress. 

What is the average price of the Kneeling Leg Curl Machine?

The price of the kneeling leg curl machine can range anywhere from $100 – $800.

What are the average dimensions of the kneeling leg curl machine?

The average dimensions can range from 46 to 49 inches for length, 50 to 60 inches for height, and 50 to 60 inches for width.

This is important because it will allow you to calculate the space required for the machine. 

What is the average weight of the kneeling leg curl machine?

  • The maximum weight capacity of hammer strength kneeling leg curls is far more than the sectorized pin-loaded kneeling leg curl machines.
  • However, they must be manually loaded which can increase client time on the machine.
  • They are cheaper than the sectorized pin-loaded leg curl machines.

How much weight can be lifted using the kneeling leg curl machine?

For kneeling leg curls that come with weight stacks, the capacity can be around 60 kg. 

For plate-loaded kneeling leg curls, the capacity is more varied. It depends upon the number of hooks and the capacity for each hook. Each hook can take anywhere from 10 to 50 kg of weight depending upon the manufacturer. If all hooks are used once, it can hold approximately 100kg. 

Will I need to buy the weights separately?

Yes, you will need to buy the weights separately if you are using a plate-loaded kneeling leg curl machine. The good news is that you may even already have those weight plates and they do not just need to be restricted to this machine. 

On the other hand, a sectorized kneeling leg curl machine will come with its weight stack that cannot be used with any other strength equipment.

Is the kneeling leg curl machine adjustable?

Yes, there are points in the machine which need to be adjustable such as the knee rest. 

You need to make sure they can be adjusted easily to ensure ease of access for the clients. Your gym will receive multiple clients and almost everyone will have different bodies. Therefore, they do need to be able to adjust the machines to their taste.

Does the kneeling leg curl machine have proper grips?

Yes, the machine needs to have grips for trainers to hold on to while executing the leg curl. You need to make sure these grips are solid and will not slip during usage. Otherwise, it can result in a major injury for your client. 

The grip material should have more friction, making it easier to hold on to. A proper material for grips these days is thermoplastic polyurethane. It improves elasticity and provides protection from oil, grease, and abrasion.

Which type of padding is used in the kneeling leg curl machine?

There are two types of padding materials used in gym equipment:

  1. Regeneration Sponge
  2. High-density foaming Material

Regeneration Foam

Regeneration sponge is recycled material used to fill the seats out. This type is not very durable and can thin out very easily. They will not last long in a commercial setting where the machine sees heavy usage.

High-density Foaming Material

In commercial settings, mostly PU high-density foaming material is used. It tends to not only be more comfortable but also more durable in high-frequency usage situations.

What type of leather should the kneeling leg curl machine have for its seat?

Synthetic leather is used in gym equipment seat coverings. There are two types of synthetic leather used in the commercial setting:

  1. Polyurethane (PU)
  2. Polyvinyl chloride (PVC)


PU leather tends to be very flexible and offers higher breathability as a seat cover. However, one of its drawbacks is that it is not very durable.

Polyvinyl Chloride 

Polyvinyl chloride leather is more commonly known as PVC leather. It is tough, durable, waterproof, and does not get damaged by frequent use. One thing that damages its perfect look is the smell that it exudes. So, check for a pungent smell when you buy the product.
