Starting Line

Think short
Don’t crawl off your couch determined to run a marathon—you’ll get discouraged when you can’t run a mile after two tries. Gross prefers “I’ll be able to run a whole mile three months from now.” Work in increments, a step at a time, depending on your initial fitness level. (Your doctor or a trainer can help assess how fit you are.)

Be specific
First, focus on one health goal—say, improving cardiovascular health by lowering blood pressure. Start with walking or biking at a nice steady pace, for 15 minutes three times a week. In two weeks, if you’re doing well, raise the duration gradually, to 30 minutes.

Pick the right moves
If you want to lick lipo, for example, strength training is a good choice. It adds muscle throughout the body, balancing—and drawing attention from—wasted limbs or a protruding belly. And extra muscle can protect your bod when you get ill by subbing for essential fat lost to lipoatrophy.

In the Zone

Make it routine
It’s like taking your meds: Set a regular, convenient exercise time and stick to it.

Do what you love
There’s no one perfect workout. If you enjoy an activity—say, ice-skating—you can build a fitness regimen out of it. If you love it, you’re more likely to stick with it.
