In school we are now doing PE every Wednesday. Try to do an hour of physical exercise at least on a Wednesday as well as keeping active throughout the week. You can do this any way you choose, walking, cycling, running etc. There is also Joe Wicks every morning if you want to join his workouts.
If you would like to continue studying gymnastics, below is a link to Youth Sport Trust. Please scroll down to the gymnastics section and complete the jumping dice lesson. There is an activity card and video for you to follow.
