The TRX suspension system is essentially a fitness tool that utilizes one's own body weight as resistance, with the full name being "Total Body Resistance Training". It relies on two straps to suspend you, and you control the difficulty by adjusting your body angle. You can exercise your entire body without having to go to the gym. This system was originally used by the U.S. Navy SEALs to maintain physical fitness in the wilderness, and later became a popular fitness equipment. Due to its portability and ease of carrying, it can now be used at home, in the office, and even in outdoor parks.

The core of TRX training does not rely on the weight of equipment, but on adjusting the angle between the body and the ground to change the difficulty. The closer the body is to being parallel to the ground, the greater the resistance. No matter what movements you do, remember these three principles: "keep the rope taut, keep your body tight, and maintain accurate positioning", otherwise you may easily get injured or fail to train properly. ‌‌

Diverse action classification: almost all muscles of the body can be trained, and there are four common categories: Upper body push-pull exercises: For example, TRX push-ups to train chest muscles, and TRX rowing to train back muscles, with the arms extended or bent to pull the body.

Lower body squats: Such as TRX squats and lunge squats, with feet on the ground or feet attached with straps, focusing on training leg and hip strength.

Core stability: For example, variations of plank and crunches, because the body is suspended in the air and unstable, the stomach must be constantly exerted to maintain balance.

Comprehensive burst: For example, mountain running, which combines cardiorespiratory and core exercises, is suitable for people who want to lose fat. ‌‌

Intensity at your own control: For the same movement, standing with your feet a bit forward makes it easier, while stepping back a bit makes it harder. Therefore, everyone from novices to professional athletes can find an intensity level that suits them. ‌‌

Training volume advice: Generally, perform each exercise in sets of 12 to 15 repetitions, doing 3 sets with a 30 to 40-second rest between sets. The specifics depend on your physical strength
