No pain, no gain? No way!
When it comes to exercise, the "No pain, no gain" mantra is bad advice. Exercise shouldn't hurt. At most, you may feel a little muscle soreness when you do a new workout or activity. If you feel pain, dizziness, nausea or shortness of breath during exercise, stop. You may be pushing yourself too hard.

Nervous breakdown: What does it mean?

Need motivation to exercise? Try a diary
Have you started a workout program? Good for you! Record your efforts to track progress toward your goals. After each workout, record these items: 1. The date. 2. Your activity (swimming, lifting weights, volleyball). 3. How long you exercised. 4. How you felt afterward. Having a chronicle of your improvement can be a great source of motivation.
Need a gym to get fit?
You don't need a gym membership to get in shape. You can fit physical activity into your daily life by doing things you enjoy outside of the gym. Play pickup basketball, go biking or walk around the park. Lift some hand weights while you watch your favorite TV show. Take the stairs at work or when shopping. Or take an exercise class through your community.
