A 21 day workout is typically divided into three different phases: strengthening, conditioning, and recovery. During the strengthening phase, the focus is on building strength and muscle tone through compound exercises. This typically includes weightlifting and bodyweight exercises, such as squats, presses, and deadlifts. During the conditioning phase, the focus is on increasing endurance and aerobic capacity. This typically includes activities such as running, swimming, and cycling. During the recovery phase, the focus is on rest and recovery, allowing the body to repair and rebuild itself after the preceding phases of the workout.
The length of each phase of the 21 day workout will vary depending on the goals and fitness level of the individual. Generally, the strengthening phase will last between two and four weeks. During this time, the individual should aim to work out four to five days a week. During the conditioning phase, the individual should aim to work out three to four days a week. The recovery phase should last the remaining days of the 21 day workout and should include rest days and light stretching.
In total, a 21 day workout typically takes around six weeks to complete. During this time, the individual will have had the opportunity to build strength, increase endurance, and give their body time to recover.
