The BEST way to practise the drums is to use HIIT timers to structure your practise. Honestly, I’ve been advocating this for a couple of years now, and those that have adopted this method (The Optimised Practise Method TM) all agree it is a powerful way to greatly improve your speed, strength and endurance.
In this video, I explain why you should be doing it too. All you need to do is set up an interval timer and prepare a list of things (I’d start with rudiments) that you want to work on. It’s as simple as that.
