It is more advanced to exercise with fitness balls and tension ropes. When most of the weight-bearing equipment is occupied by others, you can exercise with these two. Fitness balls can be used to exercise legs, buttocks and core; Tension rope can be used to exercise chest muscles, abdominal muscles, biceps brachii, triceps brachii, etc. Let me give each of you an example.

Legs: Stand, with one leg bent backward, toes on the fitness ball, the other leg bent at 90 degrees, and then get up;

Hip: Lie flat, legs bent, heel on the fitness ball, and the posterior fossa of knee is about 120 degrees. Lift hips and lower hips by the strength of hips and abdomen;

Core: put your feet and toes on the fitness ball for flat support;

Chest muscles: each hand holds a tension rope to clamp the chest;

Abdominal muscles: hold the right rope with your left hand and pull it from right to left, and vice versa; Connect the tension rope with your feet, support the ground with your hands, and roll your abdomen with your feet suspended;

Biceps brachii: each hand holds a tension rope to bend;

Brachial 3: each hand holds a tension rope to do a flat lift;

These are some examples that I can think of at present. In fact, as long as you keep fit for a long time, you can master the ways of exerting strength in various parts of muscles and how to stimulate the corresponding muscles, and you can also think of more unique fitness movements, even self-weight training, which can achieve results. Come on!
