If you play solo sports like tennis or ping pong, or golf, I do not it will help much but when you play team sports like football, you have to play in coordination and it will help you to remain disciplined.
I think walking is the best exercise if you have issues in your joint. When you walk your mental and physical health will improve. If you have a companion, it does not even feel like exercising.
My favorite team is of course my own home team. I always look forward for our national football and cricket teams to excel in international tournaments
I think there is nothing that is better than walking. When you do brisk walking, your mental health and physical health, both will improve. The best thing is it does not even feel like exercise
