The first main body 2 includes a first middle portion 21, a first left branch 22 and a first right branch 23. The first left branch 22 and the first right branch 23 respectively extend in the same direction from left and right ends of the first middle portion 21 and are parallel to each other. A first left curved portion 23 is provided between the first middle portion 21 and the first left branch 22, and a first right curved portion 25 is provided between the first middle portion 21 and the first right branch 23. Thus, one end of the first left branch 22 and one end of the first right branch 23 are simultaneously extended in a bending direction and form a bending angle with the first middle portion 21. A first supporting bracket 26 is connected between the first left branch 22 and the first right branch 23. The first supporting bracket 26 is an elastic Y-shaped plate made of thermoplastic rubber (TPR), and includes a first left supporting portion 261, a first right supporting portion 262 and a first middle supporting portion 263. One end of the first left supporting portion 261 includes a first left handle 27, which sleeves the first left branch 22. One end of the right supporting portion 23 includes a first right handle 28, which sleeves the first right branch 23.

[0017] The second main body 3 is a U-shaped tube formed by continuously bending a metal tube, and an outer periphery of the tube is enveloped by foam sponge. The second main body 3 includes a second middle portion 31, a second left branch 32 and a second right branch 33. The second left branch 32 and the second right branch 33 are respectively extended in the same direction from left and right ends of the second middle portion 31 and are parallel to each other. A second left curved portion 34 is provided between the second middle portion 31 and the second left branch 32 , and a second right curved portion 35 is provided between the second middle portion 31 and the second right branch 33. Thus, one end of the second left branch 32 and one end of the second right branch 33 are simultaneously extended in a bending direction and form a bending angle with the second middle portion 31. A second supporting bracket 36 is connected between the second left branch 32 and the second right branch 33. The second supporting bracket 36 is an elastic Y-shaped plate made of thermoplastic rubber (TPR), and includes a second left supporting portion 361, a second right supporting portion 362 and a second middle supporting portion 363. One end of the second left supporting portion 361 includes a second left handle 37, which sleeves the second left branch 32. One end of the second right supporting portion 362 includes a second right handle 38, which sleeves the second right branch 33. One end of the second middle supporting portion 363 includes a second middle handle 39, which sleeves the second middle portion 31.
[0018] The left elastic connecting member 4 and the right elastic connecting member 5 are arched bodies having openings in the same direction, and the opening direction thereof is opposite to an opening direction of the two bending angles of the first main body 2 and the second main body 3. The left elastic connecting member 4 includes an arched helical spring and a bellow tube, wherein the helical spring is used as a left spring 41, and the bellow tube sleeves and covers an outer periphery of the left spring 41 and is used as a left flexible sleeve 42. Two ends of the left elastic connecting member 4 are respectively connected to one end of the first left branch 22 and one end of the second left branch 32. The right elastic connecting member 5 includes a helical spring in an arched shape and a bellow tube, wherein the helical spring is used as a right spring 51, and the bellow tube sleeves and covers an outer periphery of the right spring 51 and is used as a right flexible sleeve 52. Two ends of the right elastic connecting member 5 are respectively connected to one end of the first right branch 23 and one end of the second right branch 33.
[0019] As shown in FIG. 3 to FIG. 9, a user can use the above structure to perform workout types including push-ups, abdominal crunches in a sitting posture, abdominal crunches in a sideways sitting posture, arm training, assisted sit-ups, presses in a sideways reclining posture, and abdominal crunches in a reclining posture, thus achieving effects of training muscles of various body parts.
[0020] Therefore, the present invention provides the following advantages.
- 1. Two main bodies are connected at the two ends of the elastic connecting members on the two sides, and are covered by a flexible material. Further, the helical springs of the elastic connecting members on the two sides are collapsible, bendable and highly flexible, such that the invention can be used as an auxiliary tool for various workout types such as push-ups. Therefore, in addition to being used for performing various types of muscle training according to user requirements to achieve different workout effects, the present invention can further effectively save costs for purchasing different types of workout equipment, save a storage space and be convenient to use and operate.
- 2. The helical springs in the elastic connecting members of the present invention are directly formed as arched in shape. Hence, not only good elasticity is provided but also sufficient bending strength is produced for prolonging durability.
[0021] One end of the first left branch and one end of the first right branch of the first main body simultaneously are extended in a bending direction and form a bending angle with the first middle portion. One end of the second left branch and one end of the second right branch of the second main body are simultaneously extended in a bending direction and form a bending angle with the second middle portion. Thus, a buffer space is formed between the main bodies and a body of the user or the ground, so as to facilitate operations and produce more stable position effects relative to the body of the user or the ground.
[0022] In conclusion, on the basis of the contents disclosed by the above description, the present invention achieves expected objects, and provides a multifunctional curved training device capable of serving as an auxiliary tool for achieving different workout effects, effectively saving costs for purchasing different types of workout equipment, saving a storage space, prolonging durability, and being convenient to use and operate.
