How long till a Lithe hiatus nixes your hot body progress?
Well, after about a month off, you'll surely be huffing an puffing through classes and feeling really weak. "Your VO2 max--the highest amount of oxygen your body can use during exercise--decreases a bit after two to four weeks, but it takes two or three months for the drop to be substantial," says Ben Hurley, Ph.D., professor of kinesiology at the Univ. of Maryland School of Public Health.
Meanwhile, your muscle efficiency and muscle mass in your arms, abs and legs really starts to shrink. So, after a month of couch sitting or not Lithing, your endurance will dip to its pre-Lithe-regimen wimpi-ness. To keep your body humming, take at least 2 classes a week!
