Need a great little morning stretch to help stretch out your hip flexers. Try this sequence.
Plank, bring your food forward between your hands for a runners pose. Bring your chest up to a lunge, drop your knee softly and press your hips forward to stretch out the hip flexers, and grab your toe for an added stretch. Hold each position for a good 10 count. OH it feels so good!
Repeat sequence with opposite leg.
