4-in-1 Leg Extension & Curl Machine for Lower Body Strength
Why We Recommend It
Tired of leg days that leave your hamstrings feeling neglected while your quads do all the work? This GOIMU 4-in-1 machine is built for home gym owners who want targeted isolation work — leg extensions, curls, hip thrusts, and calf raises — without dedicating a whole room to separate equipment. It adjusts to 47 different positions, so both a 5'2" beginner and a 6'3" powerlifter can get a proper fit. The honest trade-off: it's plate-loaded (plates not included), so you'll need to buy or already own bumper plates to use it.
What Makes It Stand Out
Target your hamstrings without neglecting your quads
Switch from leg curls to leg extensions in seconds — no unbolting or reconfiguring — so you can superset without losing momentum.
Fit a full leg workout into a 41-inch square
This machine takes up less floor space than a yoga mat, yet replaces four separate pieces of equipment.
Adjust to your exact body mechanics
With 3 seat positions, 8 backrest angles, and 28 rotary leg pad positions, you can align the pivot point with your knee joint — no more guessing.
Pros & Cons
✓ What We Love
- Linear bearings provide smooth motion even under heavy load — no jerky bushings.
- 47 adjustment points mean nearly any body size can find a comfortable position.
- Compact footprint (41x40 inches) fits in small home gyms or corners.
- Multi-functional: leg extension, leg curl, hip thrust, and calf raises on one machine.
○ Worth Knowing
- Weight plates not included — adds $100+ to the total cost if you don't already own them.
- Seat pad is on the narrower side — may feel restrictive for larger users.
- Assembly instructions could be clearer (some users report missing steps or unclear diagrams).
