For those aiming to shed some pounds, the 4-2-1 workout might just be the ticket. Tyler Read, BSc, CPT, the brain behind and a seasoned personal trainer with 15 years in the fitness sphere, shares insights on this trending workout structure. It involves a mix of four days focused on strength training, two days on cardiovascular exercises, and one day reserved for enhancing 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.”
