What should you consider when buying a commercial leg extension curl machine?

These are some points to consider when buying a commercial leg extension curl machine.

Yanre Fitness leg extension & curl machines allow for 7-adjustable positions of the seat-pad & backrest.

Comfort:

The adaptability to different users and their preferences with a little adjustment makes a commercial leg extension curl machine very comfortable & stable.

Machines that can switch smoothly between leg extensions & leg curls are the best choice.

Weight capacity:

Fitness equipment with high weight capacity is best, as it copes well with the changing requirements of the users in the long run.

Construction:

Commercial leg extension and curl machines have heavy-duty, high-gauge steel frames. The finish is either chrome or electrostatic powder-coating to make it durable & sweat-resistant.

Leg rollers:

The thigh and ankle support rollers should at least have a thickness of 3- inches or more for proper support and function during use.

Plate-loaded vs pin-loaded:

It is a matter of preference because this factor doesn’t affect the performance of the commercial leg extension curl machine.

Both types of weight loads have pros and cons, which we have discussed in the question above.

Accessories:

Commercial leg extension curl machines come with extra features (e.g.) a bottle holder or instructional placards displayed on the weight stack. 

Accessories are always an added benefit.

Yanre Fitness leg extension & curl machines come with a holder for water bottles. Some machines have trays for keys, cell-phones, etc.

Do I need to assemble a commercial leg extension curl machine after receiving it?

Yes, some parts of the commercial leg extension curl machine have to be assembled once it is delivered to you. 

All parts are clearly labeled & an easy-to-understand instruction manual is provided. Some manufacturers have online assembly guides available as well.

Wholesale commercial fitness equipment is manufactured abroad & shipped to the buyers. 

The logistics during delivery demand that the equipment is shipped to you only partially assembled.

Is the handle and base of a commercial leg extension curl machine slip-resistant?

Yes, they are.

Rubber handle bar covers and rubber foot-pads make a commercial leg extension curl machine stable and slip-resistant.
