Make out you're keen on this diet and exercise stuff. After all, fitness really should be fun. However, it is important to start any fitness program only when you feel like it. The best time is at about 2 a.m. The house is quiet; there are no distractions. The warm-up is critical. You're already an expert at stretching, so this won't be a problem. Go on with a few wind sprints, full speed, toenails clicking on the tile or linoleum floors. A few low but loud growls will help you feel charged up.
Now add some eye-paw coordination work. Find a marble (the big steelies work even better) and roll that down the floor interspersing the rolling with more sprints. See how many times you can ricochet the marble off the wall before it disappears under the fridge. Finally, work on that upper body strength with a bit of climbing. Use curtains blinds, plant hangers, or clothes. Backs of chairs work well, too. Now put it all together. A speed sprint to the end of the hall! A race around the living room! Leap to the back of the rocking chair! Let the rebound launch you to the top of the swinging planter! Rock that baby! Feel those muscles work. Just as the hook pulls loose from the ceiling, dash to the bedroom and dive under the covers. Establish your alibi just in time to hear the crash of the plant to the floor below.
Have a good Work-Out!
