@lunada729: No time to go to the gym? Then I strongly recommend this breathing dumbbell for you to try. Breathing training is essentially the training of the diragm and transversus abdominis, and just like other muscle groups, if you add weight training with dumbbells, the effect will be better. Breathing dumbb are the best way to improve muscle strength and endurance.#Fitness #perfectfigure #tiktokshop #homeexercise #share
