Body-Solid Series 2 Leg Extension & Leg Curl

2 items left

The Body-Solid S2LEC Pro ClubLine Series 2 is a full-commercial seated leg-extension and curl machine — a selectorized weight stack, all-four-side-welded frame, extra-thick DuraFirm pads and a lifetime frame warranty for the most demanding gyms.

Train your quads with leg extensions and your hamstrings and glutes with leg curls from one seated position, switching between movements in seconds — built for commercial floors, PT studios and serious home gyms.

  • Two exercises, one seated position: transition between leg extensions and leg curls quickly and effortlessly.
  • Selectorized weight stack: 72.5 kg standard, upgradable to 106.6 kg — fully shrouded for safety and a clean look.
  • Heavy-gauge steel frame with all-four-side welded construction for rock-solid stability.
  • Extra-thick DuraFirm pads for long, comfortable training sessions.
  • Full-commercial rated with a lifetime frame-and-welds warranty.
  • Ideal for commercial gyms, personal-training studios and heavy home use.

The Body-Solid S2LEC Pro ClubLine Series 2 combines two crucial leg exercises in one seamless, comfortable seated unit. The leg extension fortifies the quadriceps and patellar ligament for knee stability and power, while the leg curl targets the often-neglected hamstrings and glutes to help prevent injury, build strength and improve flexibility. Transitioning between the two movements is quick and effortless, so you spend less time adjusting and more time training, supported throughout by extra-thick DuraFirm pads.

Built to withstand the most demanding workouts, the S2LEC uses a robust, heavy-gauge steel frame with all-four-side welded construction and a fully shrouded selectorized weight stack — 72.5 kg as standard, upgradable to 106.6 kg — for enhanced safety and a sophisticated, clean look.

It's the full-commercial top of our seated leg-extension/curl range: the plate-loaded GCEC340B is the more affordable route to the same seated training, while the GLCE365B takes the alternative seated-extension / prone-curl approach.

What does the S2LEC train?
It works your quadriceps through leg extensions and your hamstrings and glutes through leg curls, all from one seated position with a quick transition between movements.

Is it selectorized or plate-loaded?
It's selectorized — a fully shrouded weight stack, 72.5 kg as standard and upgradable to 106.6 kg, so you can change weight with the pull of a pin.

How does it compare to the GCEC340B?
They share the same seated dual leg-extension/curl design, but the S2LEC is a Pro ClubLine Series 2 full-commercial machine with a selectorized shrouded stack and an all-4-side-welded frame, while the GCEC340B is a more affordable plate-loaded CAM machine.

The S2LEC's standard 72.5 kg stack upgrades to 106.6 kg. It's the only machine here with a lifetime frame warranty — and shipping is free Australia-wide, where heavy commercial machines like these normally attract freight charges (often hundreds of dollars), so the delivered price is more competitive than the sticker suggests. The GCEC340B is the plate-loaded, budget-friendly route to the same seated training. Competitor pricing (Impulse 235 lb) is current as at June 2026 and may change over time.
