All you need is a timer on your watch or phone. Start with three minutes of cardio to get warm and your heart rate up, whether it’s jogging on the spot, jumping jacks or just marching. Then it’s three minutes of legs, rotating between five each of narrow squats, broad squats, backward lunges, forward lunges and calf raises. Then on to three minutes of upper body, moving between five each of narrow push-ups, wide push-ups and tricep dips. Time to move on to core with a one-minute plank (either on your hands or forearms) and one minute of glute bridges (lifting your hips off the floor while lying on your back). For the final two minutes, just stretch out, whether that’s standing and reaching for your toes, lying on your back and moving your legs right and left like windshield wipers or sitting cross-legged and folding forward.
That’s it. Do this a couple of times a week if you can.
It’s essentially the 1%/15 minute work out. 15 minutes is literally 1% of your day and I used to do this!
From the above site I posted as the other commenter already posted the Guardian version.
