1 Machine to Train Quads and Hamstrings: A Simple Upgrade for Leg Strength

| Oct 23, 2025 / 4 min read

When it comes to lower-body training, few machines offer as much extensive versatility in such a compact space as the RITFIT PLC01. Designed to handle both leg extensions and leg curls, it provides an efficient way to target the quads and hamstrings – two of the most important muscle groups for performance, stability, and overall leg strength.

In home or studio settings where space is limited, the PLC01 excels at how quickly it transforms from one exercise to the other, allowing a smooth transition between muscle groups in a single workout.

Two Movements, One Machine

The PLC01 is built around a simple but clever mechanism: by adjusting the seat angle and roller position, you can switch instantly from a seated leg extension to a lying leg curl setup.

This makes it ideal for supersets, rehabilitation training, or efficient lower-body sessions where every second counts.

  • Seated Leg Extension: Targets the quadriceps at the front of the thigh.
  • Lying Leg Curl: Engages the hamstrings at the back of the leg, improving balance and joint stability.

    Trainer Johnnie highlighted how “the leg ext/curl machine being able to go from seated to laying is really versatile and unique,” which captures the practicality of the design – especially for home or small gym users.

Getting the Most From Each Movement

1. Leg Extensions

  • Setup: Adjust the back pad so your knees line up with the pivot point of the machine. The roller pad should rest just above your ankles.
  • Execution: Extend your legs fully while keeping your back against the pad, then lower slowly to maintain tension.
  • Tip: Focus on controlled movement – avoid swinging the weight. Holding for one second at the top helps build strength through the full range.


2. Leg Curls

  • Setup: Recline the seat flat and position the roller pad behind your lower calves.
  • Execution: Curl your heels toward your glutes, pause, and return under control.
  • Tip: Engage your core to keep your hips down on the bench – this isolates the hamstrings effectively.

By switching between these two movements, you can train the front and back of the legs evenly, reducing muscle imbalances, improving stability and lessening the potential for injury.



How to Use It in Your Training

The PLC01 fits easily into most leg or full-body programs. Try incorporating it into your weekly routine like this:

Strength Focus:

  • Seated Leg Extensions – 4 × 8
  • Lying Leg Curls – 4 × 8

Muscle Endurance / Conditioning:

  • Superset: 12 Leg Extensions + 12 Leg Curls – 3 rounds
  • Calf Raises or Bodyweight Squats – 3 × 20

Because the adjustments are quick, you can perform back-to-back movements to maximise efficiency and time under tension.

Setup and Maintenance Tips

  • Seat Alignment: Make sure the seat pivot matches the joint you’re training – this keeps movement smooth and joint-friendly.
  • Pad Position: Adjust the roller pad each session for comfort and correct leverage.
  • Load Gradually: Start light until you’re familiar with the transition between extension and curl settings.
  • Check Hardware: Tighten bolts and lubricate the pivot points periodically for smooth operation.

Following these simple steps will help maintain consistent performance and extend the machine’s lifespan.

Who It’s For

The RITFIT PLC01 suits a wide range of users:

  • Home gym owners who want maximum leg training options in a small footprint.
  • Athletes or lifters who want balanced quad and hamstring development.
  • Rehab or conditioning users needing controlled, stable movement.

It’s particularly useful for those training alone or managing recovery – the guided path provides a safe, predictable range of motion while still allowing progressive overload.

Final Thoughts

The RITFIT PLC01 makes leg day simple, efficient, and well-balanced. With its quick-switch design and smooth motion, you can train both sides of the leg in one setup – no need for multiple machines or lengthy adjustments.

Whether you’re chasing strength, symmetry, or endurance, the PLC01 delivers a compact and effective way to keep lower-body training consistent and controlled.
