Want to Give Your Workout an Instant Jolt? Try This Doctor-Approved Trick



This column features tips and advice from a revolving cast of industry leaders on hand to discuss your beauty dilemmas, from blemishes to Botox.

I’ve heard drinking caffeine before a workout can boost your performance. Is this advice worth following?

Yes, the caffeine really helps. It provides a jolt of energy that helps you get more juice out of your muscles. If you compare working out with caffeine versus without it, you can actually notice a difference. The downside is that you might feel like your heart is racing, especially if you have a sensitivity to caffeine, so this approach is not for everyone. But if you’re already used to drinking caffeine and don’t have any side effects, I recommend having a cup of coffee about a half-hour before you work out (remember, it’s a diuretic). Anything with caffeine works—it doesn’t need to be coffee. It could be a diet soda or iced tea, but a Red Bull might be a bit much. Stick to an intake of about 95 milligrams and you’ll be good.
