When the weight of the barbell needs to be adjusted, fix the barbell handle and screw the external threads of barbell handle B3, weight block A4, weight block B5, dumbbell handle 1, weight block A4, weight block B5, and weight block C6 into the internal threads in a clockwise direction. The principle is the same as the adjustment of dumbbells, as shown in the attached figure. Figure 4 shown.
[0034] The working principle of the kettlebell is as follows: the bottom of the kettlebell handle has internal threads; the upper side of the counterweight B has external threads and the lower side has internal threads; the upper side of the counterweight C has external threads and the lower side is flat. To adjust the weight of the kettlebell, hold the kettlebell handle still and screw the external threads of the counterweight B into the internal threads of the kettlebell handle in a clockwise direction; then screw the external threads of the counterweight C into the internal threads of the counterweight B in a clockwise direction, as shown in the attached figure. Figure 5 shown.
[0035] As attached Figure 6a , Attachment Figure 6b and attached Figure 6c As shown, the dumbbells have three weight levels: 5.5KG / 7.5KG / 10.0KG.
[0036] As attached Figure 7a , Attachment Figure 7b , Attachment Figure 7c and attached Figure 7d As shown, the barbell has four weight levels: 6.5KG / 8.8KG / 11.0KG / 19.2KG.
[0037] As attached Figure 8a , Attachment Figure 8b , Attachment Figure 8c , Attachment Figure 8d , Attachment Figure 8e and attached Figure 8f As shown, the kettlebell has six weight levels: 4.2KG / 5.3KG / 6.4KG / 7.5KG / 8.6KG / 9.7KG.
