Please consult your physician before beginning any stretch or exercise routine.
[The 'Rule of Thumb' is to perform 10-12 repetitions of your chosen exercise/s, e.g. 10-12 on each side. Skip any exercise that doesn't feel right. Take into account old injuries & surgeries. If it hurts, don't do it. If it doesn't make sense, don't do it. Not every exercise is right for every person. Listen to your body and rest whenever necessary.]
