My back and shoulders are my strengths. They are well-toned and do not require too much of maintenance.
But if I keep my core and back strong, the scoliosis doesn't really bother me.
When I started playing hockey, I realised the entire game relies on your back- you have to bend to play it.
Core strength and stability is very important to me. Tennis is all about rotation of the body and my ability to create power. I incorporate a lot of abdominal, back and glute exercises into my gym sessions.
If you only focus on your abdominal wall, your back isn't going to be as strong, and so there's going to be an imbalance in your body. You want them to be strong together and work together, and not have one overcompensate.
What a man needs in gardening is a cast-iron back, with a hinge in it.
Even at the age of 33 I was one of the most flexible at Arsenal when it came to my back muscles.
