A while ago, the 90-30-50 diet trend went viral on TikTok, offering tips on weight loss. Following that, TikTok introduced the 12-3-30 treadmill challenge, which has also become extremely popular. Although this trend initially gained momentum in 2020, it remains widely followed today.
Fitness influencer @michaelsheedyfitness shared that if you perform this workout for 30 minutes a day, for 30-60 days, you’ll maintain your muscles while shedding fat. A certified health coach, personal trainer, and founder of Michelle Porter explained that the 12-3-30 challenge involves walking on the treadmill for 30 minutes at a speed of 3 miles per hour on a 12% incline.
This challenge is popular because it’s simple, accessible, and highly effective for improving fitness and losing weight. It provides the benefits of cardio and lower body strength without the impact of running. Walking on a steep incline targets your glutes, hamstrings, and calves, helping to burn calories while strengthening and toning muscles. The 12% incline is especially effective for weight loss as it simulates the effort of climbing a hill.
