I. Origin stage (before the early 20th century)
● Leg training without equipment
Early strength training was mainly based on freehand squats and weighted squats.
Soldiers in ancient Greece and Rome would use stones, wooden poles, etc. for primitive leg training.
There were no special leg training equipment, and training relied on gravity and posture changes.
II. Prototype stage (mid-20th century)
● 1950s~1960s: Early Leg Press prototypes came out
The golden age of bodybuilding (such as Reg Park, Arnold Schwarzenegger) began to popularize the importance of leg training.
The early Leg Press was a vertical push-up design (Vertical Leg Press), where the trainer lay on the ground and pushed the weight up.
The structure is simple, but it puts a lot of pressure on the lumbar spine and is prone to injury.
III. Mechanical development period (1970s~1980s)
● 45-degree inclined board Leg Press appeared
It is more in line with the human body force line, reduces lumbar compression, and becomes the standard version of modern commercial gyms.
Major brands such as Nautilus and Universal began to mass produce commercial fitness equipment, including Leg Press.
The structure was upgraded to a slide rail type with a safety locking system.
IV. Diversification (1990s~2010s)
● Various structural forms appeared
Horizontal Leg Press: Commonly seen in rehabilitation centers, safe, suitable for the elderly or beginners.
Seated Leg Press: Suitable for people with joint restrictions, the feet are at the same level as the seat, and the knee load is small.
Adjustable angle and resistance system (pneumatic, hydraulic, electromagnetic resistance) appeared
Free weight Leg Press (Hack Squat + Sled) combines squat and leg press functions to stimulate larger muscle groups.
