Having common targets for training develops good relationships. Work done together has a positive effect on people, strengthens attachments and brings mutual respect. So train with people whom you like anyway. Help each other and enjoy the training, then you will improve and continue to develop. Most training sessions are a one person activity: taking 30-60 minutes, and we often do not have much time, so concentrate on this 30-60 minutes. You can chat, but then the training will last for twice as long, which becomes ineffective. I don't chat when training, I prefer to concentrate. You will find your own pace with regular training....
