I don't know what equipment you have there. Let's start with dumbbell exercises.
First, warm-up, warm-up is necessary before muscle practice, otherwise it may cause strain. Ten to fifteen minutes, run on the treadmill for a few minutes, and then stretch your muscles. You can ask the coach or check the video of muscle stretching online. It is very detailed and simple.
Second, dumbbell exercises.
Front flatbed elevator, 8- 10, 6-8. triangular
Lateral lift, ditto, deltoid muscle
Dumbbell bird, ditto, pectoral muscle
