Building muscle doesn’t necessarily require spending hours in the gym, following complicated workout routines, or investing in expensive equipment. A simpler approach to strength training is gaining attention: dedicating just 20 minutes a day to one exercise.
This minimalist training method focuses on consistency, progressive overload, and fundamental movement patterns. By rotating through a selection of exercises and using a structured training format, individuals can develop strength, improve muscular endurance, and potentially build muscle without lengthy workout sessions.
The idea is straightforward: Choose one exercise each day, train for 20 minutes, and rotate through different movements throughout the week.
What Is the One-Exercise-a-Day Workout Method?
The one-exercise-a-day method simplifies traditional strength training by eliminating the need to perform multiple exercises in a single workout.
Instead of completing an extensive routine targeting several muscle groups, each session concentrates on one movement.
The approach highlighted by calisthenics enthusiast Kace Hollingsworth uses three main principles:
- One exercise per day: Each workout focuses on a single movement.
- 20-minute training sessions: Workouts are designed to fit into a busy schedule.
- Exercise rotation: Different movements are performed on different days to develop strength across the body.
This method can be particularly appealing to people who struggle to maintain conventional workout schedules or prefer a more focused training approach.
However, its effectiveness depends on exercise selection, training intensity, adequate recovery, and continued progression.
How the 20-Minute EMOM Workout Works
One of the most important components of this routine is the EMOM training format.
EMOM stands for Every Minute on the Minute, a workout structure in which an individual performs a predetermined number of repetitions at the beginning of each minute.
For example, a 20-minute push-up session might involve:
- Starting a timer for 20 minutes.
- Performing five push-ups at the beginning of the first minute.
- Resting for the remainder of that minute.
- Performing another five push-ups when the next minute begins.
- Repeating the process until the workout is complete.
Using this example, the individual would complete 100 push-ups across the session.
The method demonstrated in the video suggests performing approximately one to ten repetitions each minute, depending on the exercise and the individual’s ability.
This creates a structured workout with built-in recovery periods.
For beginners, lower repetitions or shorter sessions may be more appropriate. More experienced individuals can gradually increase repetitions, resistance, or exercise difficulty.
Importantly, the goal is not necessarily to perform as many repetitions as possible. Maintaining proper technique and choosing an appropriate level of difficulty are essential.
Eight Exercises for a Simple Strength-Training Rotation
A successful minimalist workout program should include movements that train different muscle groups rather than repeatedly emphasizing the same muscles.
The featured approach rotates through eight exercises to address major movement patterns.
A practical eight-exercise rotation inspired by the video could include:
1. Push-Ups
Push-ups primarily target the chest, shoulders, and triceps while also engaging the core.
They can be modified by changing hand placement, elevating the hands, or progressing toward more challenging variations.
2. Pull-Ups
Pull-ups develop upper-body pulling strength, particularly in the back and biceps.
Beginners can use assistance bands or perform controlled eccentric repetitions until they develop sufficient strength.
3. Dips
Dips strengthen the triceps, chest, and shoulders.
They can be performed on sturdy parallel bars, although individuals with shoulder discomfort may need alternative pressing exercises.
4. Inverted Rows
Inverted rows strengthen the upper back, biceps, and muscles involved in maintaining shoulder stability.
Adjusting the body’s angle changes the difficulty, making the exercise suitable for different fitness levels.
5. Squats
Squats primarily strengthen the quadriceps, glutes, and supporting lower-body muscles.
Bodyweight squats are a useful starting point, while resistance can be added as strength improves.
6. Lunges
Lunges train the legs individually while challenging balance and coordination.
They also help develop single-leg strength and can reveal differences between the left and right sides.
7. Romanian Deadlifts
Romanian deadlifts, commonly called RDLs, emphasize the hamstrings, glutes, and hip-hinge movement pattern.
They can be performed with dumbbells, kettlebells, or a barbell, provided proper technique is maintained.
8. Overhead Presses
Overhead presses provide an additional upper-body pushing movement that emphasizes the shoulders and triceps.
Dumbbells, resistance bands, or appropriate bodyweight progressions can be used depending on available equipment.
Together, these exercises provide a practical foundation for developing strength throughout the body.
Why Short Workouts Can Be Effective for Muscle Growth
Muscle development depends on several factors, including mechanical tension, training volume, progressive overload, nutrition, and recovery.
A workout does not need to last an hour to stimulate muscle growth.
Shorter workouts can still be effective when they provide enough challenging repetitions and are performed consistently.
Consistency Becomes Easier
One of the biggest advantages of a 20-minute routine is that it reduces the time commitment associated with exercise.
People who find it difficult to dedicate an hour to the gym may be more willing to complete a short daily session.
Over time, consistent training can produce meaningful improvements in strength and fitness.
Focus Improves Exercise Quality
Concentrating on a single exercise allows individuals to practice proper technique and develop greater familiarity with the movement.
Instead of rushing between several exercises, they can focus on controlled repetitions, posture, and muscle engagement.
Progressive Overload Drives Results
Progressive overload refers to gradually increasing the demands placed on the muscles.
With this method, progression might involve:
- Increasing the number of repetitions.
- Adding external resistance.
- Performing a more challenging exercise variation.
- Improving range of motion and control.
- Completing the same workload with better technique.
Without progression, the body may eventually adapt to the routine, limiting further gains in muscle size and strength.
Can You Really Build Muscle With Only One Exercise a Day?
Yes, it is possible to build muscle using one exercise per workout, provided the overall program delivers sufficient training stimulus.
However, 20 minutes alone does not guarantee muscle growth.
The effectiveness of this method depends on how challenging the exercise is, the total amount of training completed, and how frequently each muscle group is stimulated.
For example, performing easy push-ups for 20 minutes may improve endurance without providing enough resistance for substantial muscle growth.
In contrast, challenging sets of push-ups performed with appropriate progression may be effective for developing the chest, shoulders, and triceps.
There is also an important limitation to consider.
Rotating through eight different exercises means an individual may train each movement only once every eight days. Depending on the exercises selected, some muscle groups may receive less frequent stimulation than they would in a conventional full-body routine.
For maximizing hypertrophy, a program that trains major muscle groups multiple times per week may be more efficient.
The one-exercise approach is therefore best understood as a convenient, minimalist training option rather than a universally superior muscle-building system.
Recovery and Nutrition Still Matter
Even when workouts are short, muscle development requires sufficient recovery and nutrition.
Protein provides the amino acids necessary for muscle repair and growth. Many resistance-training individuals benefit from consuming approximately 1.4 to 2.0 grams of protein per kilogram of body weight daily, depending on their circumstances and goals.
Adequate calories are also important, particularly for individuals attempting to gain muscle mass.
Sleep supports recovery and training performance. Most adults should aim for seven to nine hours of sleep per night.
Additionally, training every day does not mean every session should be performed at maximum intensity.
Alternating muscle groups, managing fatigue, and taking rest days when needed can reduce the risk of overuse injuries.
Who Should Try This Workout Method?
The one-exercise-a-day approach may be especially useful for:
- Busy professionals with limited exercise time.
- Beginners who feel overwhelmed by complex routines.
- People who prefer home workouts.
- Individuals interested in calisthenics and functional strength.
- Experienced exercisers seeking a simple supplementary training routine.
Beginners should consider starting with fewer minutes, using manageable resistance, and gradually increasing their workload.
Individuals recovering from injuries or managing medical conditions may need exercise modifications or professional guidance.
Final Thoughts
Building muscle does not always require long training sessions or complicated workout plans.
The 20-minute, one-exercise-a-day approach demonstrates how a simple training structure can make regular exercise more approachable.
By combining EMOM workouts, foundational strength movements, and progressive overload, individuals can create a manageable routine that supports long-term fitness.
Although this method may not be optimal for everyone seeking maximum muscle growth, it offers an accessible alternative for people who value simplicity and consistency.
Ultimately, the most effective workout program is one that provides an appropriate challenge, allows sufficient recovery, and can be maintained over time.
Twenty focused minutes of exercise can be valuable, especially when those minutes become part of a consistent, progressive training routine.
