Tabata workouts are very popular these days. High intensity, 20 seconds on 10 seconds off.
In 1996, Dr Tabata found that his subjects doing this style of training, 5 days a week for 6 weeks, resulted in a 28% increase in anaerobic and 14% increase in aerobic fitness.
I have linked to a Joe Wicks' Tabata video here, some of you may recognise him as the guy doing excellent PE lessons every morning during this lockdown - brilliant!
If you would like to do your own Tabata workouts, Circle Timer is an excellent free app to tell you when to start and stop. It's available on iOS and Android.
Oh, some more great free stuff, the people at Pepsi have offered a free set of these amazing dumbells to all CDL households! Click the picture to claim yours.
