Warm up your body with this gentle move before you really start to sweat.
How to do it: Stand with feet hip-width apart, arms by your sides. Take a deep breath in and stretch your arms overhead, pressing palms together and lifting your chest as you look up to ceiling. Exhale and slowly fold forward, opening your arms out to your sides and then to the floor (bend knees as much as needed to press hands flat on the ground).
Slowly walk your hands out away from your feet, shifting weight forward, bringing shoulders over hands and lowering torso into full plank position. Brace your abs in tight and hold for 1 count.
Gently release your hips to floor and arch your lower back, lifting head and chest to the ceiling, taking a deep breath in as you stretch. Exhale, draw your abs in tight and use your abdominals to lift your hips back up into full plank position. Hold for 1 count and then slowly walk your hands back to your feet and roll up through your spine to return to standing. Repeat as many times in a row as you can for 1 minute.
