## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an exercise machine, and more particularly to a low-impact exercise machine that provides an oscillating motion similar to cross-country skiing to improve a person's hand and foot coordination and to build strength and endurance.
2. Description of Related Art
Numerous exercise machines are currently available and include exercise bikes, treadmills, rowing machines and surfing exercisers. Conventional exercise machines simulate exercise activities and are used to exercise and train a person's muscles.
However, conventional exercise machines have some shortcomings.
1. Conventional exercise machines only have a single operation function, and only some of a person's muscles can be exercised, which limits the versatility of the conventional exercise machine.
2. Operation of the conventional exercise machine usually involves a single movement, which causes a user to become bored quickly.
The invention provides a low-impact exercise machine that mitigates or obviates the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a low-impact exercise machine that very closely replicates cross-country skiing, simultaneously improves coordination between a person's hands and feet and builds both strength and endurance.
The low-impact exercise machine has a support device, a rotating device, a drive assembly and a handle assembly. The support device has a base, a pivot pin, a frame bracket, a supporting beam and two slideways. The rotating device is mounted rotatably with the support device and has a pivot post, a rotating panel and two rotating arms. The drive assembly is connected to the support device and the rotating device and has two driven segments. Each driven segment has a linking arm, two lateral beams, an operating shaft, a mounting bracket, a connecting stick and a transmitting shaft. The handle assembly is connected to the drive assembly with two handles.
