Performing sets of 13 or more repetitions can unlock specific benefits for both you and your body.
Photodisc/ThinkstockPicture two elite athletes standing together—one a bodybuilder, the other a marathon runner. Their physiques couldn’t be more different. One boasts massive, bulging muscles, while the other is lean, almost slender, yet sharply defined. Despite their contrasting appearances, both have reaped the rewards of high-repetition workouts.
For our discussion, a high-rep workout involves performing 13 or more repetitions per set. While these workouts don’t directly enhance muscle size or strength, they boost blood flow to the muscles, foster the development of new capillaries and neural pathways, and enhance endurance [sources: Venuto, Birmingham]. For endurance athletes competing in lengthy events, the advantages are clear. For strength-focused athletes, the benefits are more nuanced. Improved circulation, endurance, and neural connectivity lay the groundwork for effective high-weight, low-rep training that promotes muscle growth [source: Apperson]. Think of it as paving the way for a fuel truck to reach its destination efficiently.
No matter your fitness objectives, high-repetition workouts can be a key to achieving them. By following these tips, you can unlock their full potential.
5: Discard the Myth
A long-standing myth, often repeated in casual conversations, claims that high-rep workouts tone muscles, while low-rep sets with heavy weights build bulk. However, science only supports part of this idea. Heavy weights with fewer repetitions indeed promote the most muscle growth. As for toning, the belief that high reps are the solution is misguided [sources: Birmingham, Norton].
A toned muscle appears firm and defined. For it to be visible, it must not be obscured by a layer of fat. Therefore, your focus should be twofold: reduce fat and build a solid physique. Effective fat loss is best achieved through cardio exercises that burn significant calories [source: Birmingham]. Activities like cycling, running, or cross-country skiing are far more efficient for this purpose than repeatedly lifting light weights. While high-rep workouts can contribute to muscle development, low-rep exercises will help you achieve your goals faster.
Concerned about gaining too much bulk? Many aspiring bodybuilders wish it were that simple. Achieving significant size requires intense dedication and months, if not years, of consistent effort. Incorporating a few low-rep, high-weight sessions into your routine won’t suddenly transform you into a massive figure [source: Valluzzi].
While high-rep workouts offer numerous advantages, toning isn’t among them. Letting go of this misconception will help you optimize your workout time effectively.
4: Determine Your Discipline
The amount of time you dedicate to high-rep workouts depends entirely on your preferred sport or discipline. Preparing for a cross-country cycling event? Great. Including high-repetition strength training in your regimen will help your muscles store more glycogen, which your body converts into energy. Training for a marathon? The additional capillaries formed through high reps will enhance oxygen delivery to your muscles, sustaining you through those grueling miles. Aiming to dominate a powerlifting competition? Focus primarily on heavy weights and low reps (1 to 5), which engage all muscle fibers for maximum strength [source: Norton]. Bodybuilders, on the other hand, fall between endurance athletes and powerlifters. They achieve optimal growth by focusing on moderate reps (6 to 12) while still benefiting from lighter, high-rep sets [sources: Venuto, Norton].
If your goal is to look great at the beach rather than compete, consider which athlete’s physique you admire most. Ultimately, it’s a personal preference, and you don’t need a medal to turn heads.
Although a bodybuilder might seem larger and more powerful than a competitive weightlifter, the weightlifter typically outperforms in lifting heavier loads [source: The Weightlifting Encyclopedia]. This difference stems from their training methods. Strength gains, driven by neurological adaptations, occur with very low reps and extremely heavy weights. In contrast, visible muscle growth is more pronounced with moderate reps and slightly lighter weights [source: Venuto]. In essence, perception (the bodybuilder’s size) often outweighs reality (the weightlifter’s strength).
3: Focus on Form
High-rep workouts don’t justify poor form. Proper technique is one of the most critical aspects of fitness. It ensures the right muscle groups are engaged and plays a major role in preventing injuries [source: Stefano]. The lighter weights used in high-rep exercises should allow you to maintain a full range of motion, whether you’re performing squats, deadlifts, curls, or other movements.
However, there’s a risk in equating high repetitions with high speed. If you’re moving so fast that your movements become uncontrolled—swinging, jerking, or flailing—you’re inviting injury. Performing 20 reps with proper form is far more valuable than rushing through them.
2: Get Creative With Circuits
Circuit training offers a quick, intense, and rewarding workout experience.
Hemera/ThinkstockAny exercise regimen can become dull over time. Additionally, when time is limited, it’s tempting to skip the most repetitive tasks. However, high-rep workouts offer a solution. By designing your own circuit training plan, you can stay creative and efficient, saving time while keeping things fresh.
Choose six exercises and perform one high-rep set of each with minimal rest in between. For instance, you could start with 30 push-ups, move to 50 sit-ups, then 25 squat thrusts. Follow this with 30 calf raises (both legs together), 20 curls per arm, and 25 tricep extensions per arm. This approach delivers a demanding workout that keeps boredom at bay and takes only about 15 minutes of your day [source: Marinello].
1: Remember Who Wins
The fitness industry is full of debates. Discussions about the best exercises, equipment, and even the ideal number of repetitions happen daily in online forums, coffee shops, and gyms. Often, these disagreements are just about terminology. (For example, if one person considers 10 reps moderate and another sees it as high, they’re essentially agreeing.) However, conflicting advice can make you want to quit your workout routine altogether. That’s the worst mistake you could make.
If high-rep workouts are a significant or primary part of your fitness routine, stay committed. Consistency is key. Someone who fully dedicates themselves to an intense program but frequently quits will achieve less than someone who integrates a steady, manageable plan into their daily life [source: Horton]. The true winner in any fitness discussion is the person who stops debating and starts working.
