So, I am halfway through 30 day challenges for squats and a couple of sob-inducing core exercises (planks and leg raises. I don't half hate leg raises), with the vague idea that it might improve my running.
No idea if it's phsychosematic, but I've gone down to eight and a half minute miles and I'm really chuffed.
Anyone else who fancies joining in, the free '30 days' app is fab as you start with a test so it tailors the challenge to your current fitness.
