Everything You Ever Wanted to Know About Exercise
Q: How often do I need to buy new workout shoes?
A: The general rule is every 500 miles, but sneakers tend to last longer if
you're using them on cardio and weight machines versus pounding the pavement
with regular outdoor runs.
Q: How many calories should I expend each day to lose weight?
A: To lose 1 pound a week you need to expend an additional 500 calories
a day, either through exercise or cutting calories from your diet. Don't try to
lose more than 2 pounds a week — people who lose weight quickly tend to regain
Q: If I have only 30 minutes, what's the best way to utilize that time to
burn the most calories and fat?
A: Work out at the high end of your target heart rate zone doing
anything that gets you up to that level, whether it's doing one cardiovascular
activity or a combination of activities.
