Climbing stairs, standing on one foot, skipping rope, skiing, cycling, squatting, squatting, jogging, walking in shallow water, all kinds of aerobics, and even taekwondo can all be used to exert your imagination.
If you can, choose what you like and what you can stick to.

Pay faster, no pains, no gains.
Stick to it and wish you success!
