Try to get outside as much as you can and get some fresh air. Go for a walk or a jog around the block or in the garden, get out on your bikes, roller skates or to the park. There are lots of Just Dance videos on you tube for in between your learning . You could even play catch with a pair of socks inside ( if that is ok with your parents) to practise your catching skills or make a target to throw something at in the garden or at the beach. I have put some links to some HIT workouts which are fun for all the family and you can do them in any order you like.
