I began to play sports at home as all gyms are closed. But I'm not so neat without my coach. My muscles are on fire today. What have I done wrong? I want some advice.

I will say directly - I have a weak motivation for playing sports at home. In addition to this, there is another reason - the high invasiveness of bodybuilding. You always need someone who will ensure you during the exercise. By the way, I damaged the joint once when I took too much weight. I had to take green roads. This natural pain medication helped me recover faster, but the memory of such a failure in training was a good lesson for me.
