Injuries can occur due to a weakness or lack of mobility especially in the arm. Choose either the elbow, wrist, or hand and describe an exercise to stretch and an exercise to strengthen the muscles that surround that joint. What muscles are specifically being targeted?
Kim Bok Joo is training to be a world-class weight lifter. But as part of her routine, she has cross-training in swimming twice a week. Aside from getting a swimmer boyfriend, why is cross-training important for an athlete like Kim Bok Joo?
Two identical twins go to the gym a lot. One stretches, does yoga, and then goes for a long slow swim. The other lifts heavy weights, alternates sprints with jogging on the treadmill, and then lifts some more. Contrast their general body contours and the anatomy of their musculoskeletal system after two years of these regimens, and explain the mechanisms responsible. Assume no weight change for either of them.
