When you’ve been sitting all day…
Use anything but the stationary bike. “If you spend a significant part of your day sitting at work, the last thing you need is to be seated through your workout,” says Rosante.
Because you’re sitting, you’re also not working as hard—you’re at a 10 percent diminished capacity, says New York Area Board Certified Personal Trainer and Nutritionist Franci Cohen. “You’ll need to make up for this with resistance,” she says, or a longer workout. Try the treadmill or elliptical instead.
