Exercise with a rowing machine. Using a rowing machine will help you burn calories and tone your arms. To use the machine, strap in your feet and reach forward to grab the handlebar. Keep your back straight and your knees bent. Push off with your legs and pull the handlebar toward your chest. Then, extend your arms and bend your knees again as the handlebar goes back to the starting position.
McAlpine's favorite on-the-go exercise is a classic for a reason: Push-ups are one of the most effective bodyweight exercises around. "Primarily, this move will target your chest, triceps, and your anterior deltoid muscles (the front of your shoulders)," says McAlpine. It also seriously works your core. Plus, there's something that just feels badass about working on push-ups and seeing yourself improve over time. "I personally love that feeling of strength that comes from this simple move," says McAlpine.
When talking with some of our trainers, squats were almost unanimously recommended for working out with no equipment. Mike Septh told us, (“I’m a firm believer in performing movements that require the most muscle recruitment that in turn burn the most calories.” Kelly Chase said, “They tone, tighten and firm up your whole body, especially your legs/booty.”
If you cannot hold the starting position, modify it by dropping to your knees, keeping your arms and shoulders straight. Keep your head in alignment with your back and lower your chest towards the floor. Your elbows should be tucked into your sides as you hover over your fingertips. It’s completely fine if you can only lower your body a few inches. The more often you do tricep push ups, the easier they become.
One doesn't automatically associate regular exercise with a reduction in the number of colds people get. But researchers from the University of Carolina found that people who exercised regularly were 23% less likely to get colds than those who exercised less. And if those who exercised got colds, the symptoms disappeared more quickly than in the study participants who did little exercise.
