8. Your Own Body Can Be the Best Tool!

The Trick:

Use your own body weight to get some quick strength training.

Why It Works:

Of course, you can invest in equipment like weights and dumbbells that you’d need for strength training, but as a beginner, you could just start by using your own body weight. Avigdor Dori Arad, RD, a certified exercise physiologist at Mount Sinai St. Luke’s hospital in New York City, says that exercises like push-ups, sit-ups, squats, and etc. are great ways to use your own body as a tool of resistance. “Body weight exercise is cheap, adaptable, simple, and doesn’t require much space,” he says, “[They] can help you become lean, active, and strong.”
