Good afternoon,
To prepare for bleep test i would say start with interval run,for example, 20 sec sprint 20 sec rest gradually increase the time,try to do this for 12-15 mins on alternate days.Remember rest is equal importance to relax your muscles, and Make sure to warm up before you start and proper stretching once you done to avoid injuries.

I echo this answer. Also, if you play a sport such as netball, basketball, football, where you have to do shuttle runs that will help. I know this is hard at the moment but if you could do the drills involved in these sports this would help too. Any HIIT workouts will be good for you asw well. You will get out of breath, that is normal, you just have to get used to it and push through it. With practice you will get better. Good luck.

Thankyou very much
