At the urging of a neighbor, Evans visited Reebok CrossFit 365 in Skewen, South Wales, at the age of 92. Since then, he’s come into the box every Monday, Wednesday and Friday. “I think when people get over a certain age, they think, ‘Oh, I shouldn’t really do that because I’m too old.’ But you’re never too old, and it’s never too late to start.”

When we teach about the heart, we differentiate between the structures and functions of its right and left sides. The major functional difference is that the right side of the heart delivers blood to the lungs and the left side delivers blood to the rest of the body. The right side’s purpose is pulmonary circulation, and the left side is responsible for systemic circulation.

In the duration of a warm-up, there are uncountable opportunities to weed out bad mechanics. Pulling with the arms, not finishing hip extension, failing to shrug, pulling too high, lifting the heels in the first pull, curling the ball, losing back extension, looking down, catching high then squatting, slow dropping under, slow elbows — all the faults are there.

Functional movements are optimal for developing human bodies to their highest potential. By virtue of recruiting as much muscle as possible, these movements uniquely equip a person to perform more work in less time. Calorie burn is a measure of work, so it can be said that functional movements burn calories at a faster rate than non-functional movements.

Blood vessels are adaptable to stress. If there is hypoxic stress (low oxygen content present) that results in tissue hypoxemia (low oxygen in the tissue), a cascade of local hormonal and anabolic events occurs that produces new capillaries and new arterioles. This process is called angiogenesis and is considered to be an endurance-friendly anatomical adaptation, improving the body’s capacity to deliver oxygen to working skeletal muscle.
