Days 6 - 14. As your estrogen levels rise during the follicular phase of your cycle, you should start to feel happier and more energised. This is the phase we work hard, this is also known as the power phase and I encourage you to make the most of each day. This Phase includes our Power workouts, sculpt and HIIT. Feel free to increase the weights, include some extra cardio and focus on eating lots of protein. This is a perfect time to set new habits and goals.
