Hurting your arm does not mean you cannot work it out. If you focus on your opposite arm you can still build strength in the injured arm. This happens because when you work out one arm, the muscle nerve fibers in the other arm are stimulated as well. By training the healthy arm for a couple of weeks while healing, you can see upwards to 10 percent strength gain in the injured arm.
A great tip to get physically fit is to take the stairs wherever you go. Climbing stairs is one of the best exercises you can do to get in shape. Next time you're at the mall or department store, take the stairs instead of the elevator or escalator.
If your fitness routine includes outdoor exercise, be prepared for the shorter winter months by kitting yourself out with equipment for night-time workouts. Reflective clothing improves your visibility and protects you from traffic. Lights are vital for biking, and indeed can be handy no matter what kind of exercise takes you into the darkness.
