One thing that I have started to do more of is sprint training??. I will admit I find it hard to do this by myself. I like to have someone with me doing it together. Make sure you have a water bottle, pump up music, my HIIT training open on the @sweat app and the right shoes done up correctly!! I sprint 30 seconds on - 30 seconds off for 15 minutes! www.kaylaitsines.com/app
