If you only have twenty minutes to workout on a given day, you can still get a lot accomplished if you choose the right cardio equipment. Bally trainer Tasha Williams ranks her top three picks.

I would say the first, the treadmill, cuz you do burn the most calories on the treadmill. 

Although it varies for each individual, it’s tough the beat the treadmill for total caloric expenditure, when comparing it to other exercises done for thirty minutes at a moderate intensity. Tasha’s second recommendation is the elliptical cross-trainer with arm bars, as you’re using your upper and lower body. Her third choice—the stair climber, done properly, with good form.

As you step, you want to think about contracting your buttox and your legs to get the most effective workout. Keep your abs in nice and tight, shoulders down, chest lifted and hands off of the bar. For Inside Fitness, I’m Bonnie Kaye.
