[0002] Exercise and weightlifting are very important for maintaining good physical and mental health. Exercising the core muscles and tendons is particularly beneficial for the spine and posture. Home gyms and equipment can take up a lot of space and may rely on heavy weights, resistance bands, ropes, etc. Many exercises rely on one's own body weight and need to be performed on the floor or require flexibility. Usually, a large number of repetitions and a significant time investment are required to see significant results. The back muscles, tendons, and ligaments take longer to strengthen than other muscles. Many people thus abandon their fitness goals, leading to a decline in the quality of life. The fitness industry needs a handheld device that can effectively and efficiently help enhance strength and build muscle, using only a fraction of the weight, without the need for resistance bands or relying on body weight, and can be used by anyone who can move their arms or wrists. The present utility model is a handheld exercise device that can show and be felt the effects by using weights in a short time. This device is suitable for people of any age and any fitness level. The invention can enhance strength, target the core muscles, tendons, and ligaments, and improve balance and posture. There is no need for expensive heavy equipment, resistance bands, or relying on body weight. This exercise device is very compact and can even be used in bed. This exercise device can replace the use of heavy weightlifting, resistance bands, or one's own body weight. The effects can be seen and felt without a large time investment or strenuous repetitive movements. This device will make exercise more convenient, efficient, and effective, suitable for everyone to use.

[0003] One objective of the present utility model is to provide a multifunctional handheld exercise device. This handheld exercise device has multiple configurations and can adapt to users of any age, strength, or characteristics that may affect their ability to use complex weightlifting equipment (with a limited weight range).

[0004] Another objective of the present utility model is to provide an efficient and effective exercise device. The present utility model is small and compact, easy to store, but can provide users with sufficient weight and versatility for a comprehensive workout. Summary of the Utility Model
