Packed my sauna suit and skipping rope into my pannier bag this morning. Soon as I finished work, I got changed into my sauna suit and set up the interval timer on my android phone and had a 20min session in the work car park.
5 secound sprints followed by 30sec slow and steady. Rinse and repeat.
I was drenched in sweat by time I was half way through. Cycled home as my cool down. Next time I intend to add ankle weights to the mix.
