Secondly, if you want to use training equipment, girls can choose dumbbells that are not so heavy for training. On the one hand, they can exercise your strength, on the other hand, they can exercise your hip muscles.
Third, if a girl starts training and the dumbbell is too heavy for you, you can choose to lift the dumbbell with one hand and find a place with a fulcrum for assistance with the other hand.
Fourth, of course, you can also choose a place close to the wall to train your hips, with the wall as the support, put your legs on the wall, and then hold your arms on the ground to do push-ups and lift your hips up and down.
