Description

Gronk Fitness Leg Extension / Leg Curl

The Gronk Fitness Leg Extension / Leg Curl is a compact plate loaded lower body machine built for quad and hamstring training in home gyms, residential fitness spaces, and light commercial facilities.

This dual function leg machine switches quickly between leg extensions and seated leg curls, using Olympic weight plates for progressive resistance with no cables, pulleys, or weight stacks to jam.

Key Features

  • Dual function design trains leg extensions and seated leg curls on one compact machine.
  • Targets quadriceps and hamstrings for balanced lower body strength development.
  • Plate loaded resistance supports progressive overload with Olympic weight plates.
  • 23 pin-lock adjustment points help fine tune positioning for proper alignment.
  • Heavy duty 11-gauge steel frame improves stability during focused leg training.
  • Premium contoured upholstery and oversized rollers support comfort during repeated sets.
  • No pulleys, cables, or weight stacks help reduce maintenance and improve reliability.
  • Transport wheels make repositioning easier in compact gym spaces.

Exercises

Use this machine for leg extensions and seated leg curls to build quadriceps, strengthen hamstrings, improve lower body muscle balance, and support controlled rehabilitation-style training.

Who This Is For

Ideal for home gym owners, athletes, recreational lifters, and light commercial training spaces that need efficient lower body strength training without a selectorized weight stack.

What do G&G customers say?

Thank you for helping me pick out the perfect treadmill. It’s so nice to be able to run on hot or bad weather days or late at night…it fits perfectly in my house and is just right for my runs. I’ve used it to keep up with my physical therapy schedule and I’ve lost over 60 lbs since I got the treadmill! Thank you!

I have 20 years of working in the physical education, coaching, and health profession. My experience with G&G Fitness has been unmatched. The staff went the extra mile by demonstrating superior equipment knowledge, as well as safe and effective exercise programming. Their unparalleled commitment to helping me meet the needs of my fitness program within limited space and budget was top notch.

Tom & Lori

In this competitive retail environment, customer service is extremely important. Karen and I appreciated your ‘non-pushy’ approach and expert advice when we were making our decision to purchase. The delivery and set up went fine, and so far....everything is going great! Thanks again for everything
