The Truth Behind the 12-3-30 Workout: Expert Opinions on the Treadmill Fitness Trend
Originally Published 2 years ago — by New York Post
The 12-3-30 workout, which involves walking on a treadmill at a 12% incline and a pace of three miles per hour for 30 minutes, has gained popularity on TikTok. While it may seem simple, this low-impact exercise can provide numerous health benefits, including reducing the risk of heart disease and dementia. The steep incline helps burn more calories and build muscle in the glutes, quadriceps, hamstrings, and calves. However, experts advise gradually working up to the full workout to avoid strain or injury, and caution against attempting it if you have knee problems. Completing the 12-3-30 workout five times a week meets the recommended guidelines for moderate-intensity activity, but it's also important to incorporate muscle-strengthening exercises.
