Start standing at the back of your mat with your feet hips-width apart.
Engage your core and keep your back flat as you bend forward, hinging at your hips to bring your hands to the mat. This position brings length to the back of the legs. If your hamstrings are tight, bend your knees a bit to take tension off the muscles.
Walk your hands forward, moving into a plank, and hold each step to stretch your calves a bit. This warms up the shoulders and hands nicely.
Hold the plank for a few seconds to really wake up your core.
From your plank, walk your hands back to your feet until you are in another forward bend. Slowly roll up to standing, letting your head hang and keeping your neck relaxed. This counts as one rep.
