What is the 4-2-1 workout method?
If your fitness goal is to lose weight, this program structure may be an excellent one to try. “The 4-2-1 combo workout is a popular workout program template currently trending on TikTok,” explains Tyler Read, BSc, CPT, the founder of PTPioneer.com and a personal trainer who has been involved in the health and fitness world for the past 15 years. “The idea is that you do four days of strength training, two days of cardio, and one day dedicated to mobility.”
The strength training portion of 4-2-1 helps you maintain and sculpt muscle mass—especially if you’re dieting for weight loss and want to avoid too much muscle loss. Adding more muscle to your frame also boosts your resting metabolism, further supporting your fat-loss efforts. “The two days of cardio are helpful for both general fitness and burning more calories,” Read adds. “Finally, the mobility day is a great way to help with injury prevention and recovery, especially if you are fully following the rest of the program and working out a full six days per week.”
Trainers love the 4-2-1 workout method to burn body fat.
Trainers and fitness pros on TikTok can’t get enough of recommending the 4-2-1 workout method for fat loss.

All you need is a set of dumbbells and 30 minutes.” This video raked in more than 508K likes.
