You don't need anything to drink water and wipe your sweat. Don't learn from others. You spend a lot of money on equipment. In this way, you will not be able to use or need to use common protective devices, such as knee pads, knee pads, elbow pads, bench-press slings, etc. These protective devices limit the mobility of joints and provide flexibility. Then you don't need to wear heavier weight with lighter weight. The muscle tension pushed upward by the elastic force of the protective gear is basically unchanged.

Wrist protectors are still useful.

The above premise is that for you.

Not to mention what is good, not to mention that the belt can't protect the waist at all. If you want to bend down, you don't have to bear any weight at all. When you relax, you will bend it. This is a kind of squat shoe, which is used to keep the abdominal pressure in harmony with Waals' breathing. Also choose the one that suits your arch. Generally speaking, to sum up, the ankle and hip joints are not active enough or want to reduce the exercise stroke when squatting. The function of protective gear is to give you a little reminder and help when you can use it. Attention is the most important supplement to support your own strength. You don't need to supplement when you start training. The shape and quality of supplements are not as good as natural foods, not to mention the metabolism has not changed. I recommend your "equipment": anatomy, physiology and nutrition.
