Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment structures, in particular to a leg dumbbell trainer. Background Art

[0002] With the increasing popularity and development of fitness, people's demand for fitness equipment is becoming increasingly diverse. Traditional fitness equipment such as treadmills and exercise bikes, while providing a full-body workout, can be less precise when targeting specific areas like the legs. Consequently, a variety of fitness equipment specifically designed for leg training has emerged on the market, with leg dumbbell trainers, among them, garnering widespread attention for their unique training methods and effectiveness.

[0003] Tools for performing leg exercises are complex, heavy, expensive, and take up a lot of floor space. People who perform exercises at home do not have access to these leg training tools and may skip or not perform these exercises, which results in an incomplete physical training process.

[0004] Existing leg dumbbell fitness trainers combine the features of dumbbell training and leg training, making them suitable for indoor training in small spaces. The weight of the dumbbells provides resistance, allowing the leg muscles to be trained in the process of overcoming the resistance. However, existing leg fitness trainers usually tie the weights to the legs, resulting in uneven force on the legs and poor training results. Existing shoe-type training devices are difficult to fix and install, and are cumbersome to put on and fix, making them inconvenient to use.

[0005] A novel leg dumbbell training device is now needed to solve the above-mentioned problems. Utility Model Content
