When it comes to building muscle, the pursuit of faster and more effective methods is never-ending. Recent research suggests that using “bad form” might be the key to gaining muscle almost twice as fast. But before you throw out everything you know about proper form, let’s dive into why focusing on the stretch position of your exercises can dramatically enhance muscle growth.
How to build muscle.The Science Behind Muscle Growth and the Stretch
Traditionally, proper form is emphasized in resistance training, ensuring full range of motion and controlled movements. However, recent studies, including insights from Dr. Milo Wolf, a leading expert in this field, suggest that the stretch position during exercise plays a critical role in muscle hypertrophy. According to Dr. Wolf, about 10 to 12 studies have shown that training a muscle group in its stretched position can lead to nearly double the growth compared to traditional methods.
But why is the stretch so crucial? When a muscle is stretched under load, it creates a unique stimulus that enhances muscle fiber recruitment and growth. However, many people, even experienced lifters, often neglect the stretch position because it’s the most challenging part of the movement. For example, during a bench press or squat, the deepest part of the movement is where the muscles are most stretched, yet it’s also where people tend to cheat by shortening the range of motion.
Why Bad Form Might Be Good for Growth
We’ve all seen someone in the gym doing half-reps, and usually, this is frowned upon as poor form. But what if those half-reps were done in the stretch position? It turns out, this might actually be beneficial for muscle growth. Research shows that focusing on half-reps during the stretch phase of a movement can lead to greater hypertrophy compared to full range of motion exercises.
For example, consider calf raises or lat pulldowns. These exercises are often most challenging at the end of the movement when the muscles are fully contracted. However, research indicates that the beginning of the movement, when the muscle is most stretched, is more critical for growth. In studies on calf exercises, performing only the bottom half of the movement resulted in approximately twice the muscle growth compared to full range of motion.
How to Maximize Muscle Growth with the Stretch Strategy
To harness the power of the stretch for faster muscle growth, there are a few key techniques to implement in your training:
1. Choose Exercises That Maximize the Stretch
Not all exercises are created equal when it comes to stretching the muscle. For example, a barbell bench press may limit the stretch on the chest muscles because the bar stops when it touches the chest. Switching to dumbbell bench presses can allow a greater range of motion, thereby increasing the stretch. To push this further, exercises like deficit push-ups can eliminate the restriction of the barbell or floor, allowing an even deeper stretch.
For biceps, compare the preacher curl with the incline curl. While the incline curl stretches the biceps more because the arm is positioned behind the body, preacher curls create more tension at the bottom of the movement where the biceps are stretched. Studies have shown that preacher curls lead to more growth, especially in the lower biceps, because they challenge the muscle in the stretched position.
2. Focus on Resistance in the Stretch Position
When choosing exercises, prioritize those that maintain resistance during the stretch. For instance, dumbbell flies are a great chest exercise because they are most challenging when the chest muscles are fully stretched. Similarly, overhead tricep extensions for triceps and reverse cable flies for rear delts also emphasize the stretch position.
If the stretch position feels easy or lacks resistance, it’s likely not the best choice for maximizing hypertrophy. The goal is to find movements where the stretch position is the hardest part of the exercise, as this will yield better muscle growth results.
3. Incorporate Half-Reps in the Stretch Position
For exercises where the contracted position is the most difficult, such as rows or lat pulldowns, try incorporating half-reps that focus solely on the stretch position. After completing your full range of motion reps, continue with half-reps in the stretched position until failure. This method has been shown to significantly boost muscle growth, particularly in the muscles that are hardest to target, such as the calves and lats.
The Future of Stretch Research and Muscle Growth
While the research is promising, it’s still in its early stages. Currently, it’s unclear whether all muscles benefit equally from stretch-focused training or if certain areas of the muscle see more growth. However, the potential is significant enough that further studies are being conducted. For example, new research at the University of British Columbia is exploring how challenging the muscles in the stretch position impacts growth, using custom machines that can alter resistance based on the position of the exercise.
A Smarter Way to Build Muscle Faster
Building muscle doesn’t always require more weight or more reps. Sometimes, it’s about working smarter, not harder. By focusing on the stretch position in your exercises, you can potentially double your muscle growth. Whether you’re adjusting your technique to maximize the stretch or incorporating strategic half-reps, these methods can help take your muscle-building efforts to the next level.
For those looking to optimize their training, consider integrating these stretch techniques into your routine. And for those who want a more guided approach, following a science-backed program that incorporates these principles can simplify the process while maximizing results.
The next time someone tells you that “bad form” is bad for growth, remember that it’s not about the form itself, but how and where you apply the tension. By focusing on the stretch, you might just unlock faster muscle growth than ever before.
