Best yoga pose for your chest and back: Four-limbed Staff
Why: This pose isn't for the faint-hearted. A real upper body toughie that challenges core too.
How: Start in a push up position but with your hands positioned further down the body than they usually would be for a standard push up. Keep your hands tucked underneath your armpits, close to your sides, with your elbows bent throughout. Your weight should be distributed between the palms of your hands and the balls of your feet with your body forming a straight line from shoulders to ankles. Hold for up to 30 seconds. Rest. Try and repeat to a total of three times.
