We could write you a whole paragraph about biomechanics, muscle activation and progressive overload, throw in a chart or two and a word like "proprioception", but we won't. The Temper Resistance Band doesn't come with an app, or a subscription, or a voice in your ear telling you you've got this. You might not love to use it, and on the days you need it most you'll probably hate it a bit, but it's usually the difference between playing next week and explaining to everyone why you're not.

It comes in two strengths, 5 kg and 15 kg, and how you use them is up to you. Take one on its own or get the bundle. Made from 100% natural latex, light enough to live in your racket bag and get forgotten there. Keep it out of the sun and away from anything sharp, and it'll outlast most of your excuses.

Warming up is part of the game!
