1. Lie on your back on the stool surface, with your legs bent, your feet slightly wider than your shoulders, and your whole feet supported on the ground, holding your chest out and abdomen in. Bend your arms, cross your hands over your head, hold the inside of one end of the dumbbell, palm up, and the dumbbell droops.

2. Hold the bell with both hands. When the elbow slowly bends to the top of your head, the elbow gradually bends until the upper arm is in a horizontal position, and the angle between the upper arm and the lower arm is about 100-120 degrees. When the dumbbell drops to the lowest position, use the strength of pectoralis major and latissimus dorsi to lift the dumbbell along the original path until the arms are straight in front of the chest.

The following is a hand clap: this action is one of the standards of chest muscle training. I can only say that I can exercise latissimus dorsi, deltoid and triceps brachii.

If it's specifically for latissimus dorsi

Instruments: rowing in a sitting position, straight arm pull-down, and sitting position pull-down.

Barbell: Barbell bends over (including T-bar, Smith bends over).

Dumbbell: One-handed bending dumbbell rowing

The most classic, convenient and available in any perfect community: the horizontal bar pull-ups

To sum up, multi-group movements and multi-group training are important factors of muscle exercise. If there is not much equipment, then pull-ups and dumbbell rowing are your best choice!
