a warm up and cool down are not included, please warm up first. Join me for my new 17 min fat burning HIIT Reshape workout which includes step intervals and medium to high intensity intervals using just body weight. HIIT Reshape will increase your heart rate and does come with low options if needed. The step is optional or you can use the bottom step of your stairs or jogging on the spot. This motivating short workout moves you in all directions and targets the whole body.
