Stretching is probably the most overlooked exercise ever. People often finish their workouts and just walk out… not taking the time to stretch. Stretching will increase your speed (as the increased range of movement equates to a larger stride), increased mobility, decreased injury and a speedier muscle recovery after training. It is also important to know that as we age our flexibility decreases and this is one of the biggest causes of our physical aging, stopping us from being able to perform everyday tasks. So make sure you stretch after every workout and add the occasional stretch in on its own after warming up, it is very important never to stretch a cold muscle.
Here are some stretches to add to your collection.

Disclaimer: As with any type of physical activity, it is advised you warm up for 5 minutes before commencing exercise, followed by 5 minutes of stretching upon completion. These exercises are designed as a basic guide and professional consultations should be taken before commencing any exercise.
