Jennifer Cornelius, a medical doctor and yoga instructor, says the practice of Savasana can be a great way to end a workout session at home, particularly in winter. Savasana is when you lie in the 'corpse pose', and it can be practised on its own or at the end of a session. Use a timer, she says, as this will allow you to fully relax without worrying you'll end up falling asleep. All you need is a quiet space, a comfortable surface to lie on, a pillow for your head and another for underneath your knees. Lie on your back, arms at your sides but not touching your body, palms facing up, legs relaxed with feet splayed. You should feel expanded, as if you're taking in as much of the room space as possible. Take up to 20 steady breaths, gradually increasing the length of inhalations and exhalations. Then completely let go, release any controlled breathing and mentally allow your body to 'sink' into the floor. Observe your thoughts without reacting to them. After 15 minutes, roll onto one side and use your arms to sit up slowly.
