3 Ways to Use Strict Curls to Build Bigger and Stronger Biceps

The pursuit of bigger and stronger biceps is a common goal among fitness enthusiasts, bodybuilders, and athletes. While there are countless exercises available to target the biceps, one exercise stands out for its ability to isolate and engage the biceps like no other: the strict curl. In this article, we’ll delve into three ways to use strict curls to build bigger and stronger biceps, backed by scientific evidence and practical advice to help you maximise your gains.

What Are Strict Curls?

Strict curls are a bicep exercise that involves curling a barbell, EZ curl bar, or dumbbells with a strict form. This means eliminating momentum by keeping the back against a wall or other surface, locking the elbows in place, and focusing purely on the contraction of the biceps to lift the weight. The strict form ensures that the biceps are the primary muscle group working during the exercise, reducing the involvement of other muscles like the deltoids or lower back.

Why Strict Curls?

Strict curls are particularly effective for building the biceps because they minimise cheating and isolate the biceps to a greater extent than other curling exercises. By enforcing strict form, you reduce the potential for other muscle groups to assist, thereby maximising the tension on the biceps. Research has shown that greater muscle activation leads to improved muscle hypertrophy (growth) and strength gains over time (Schoenfeld et al., 2017).

1. Implementing Progressive Overload with Strict Curls

Understanding Progressive Overload

Progressive overload is a fundamental principle of strength training that involves gradually increasing the stress placed on the muscles over time. This can be achieved through various means, such as increasing the weight lifted, the number of repetitions, or the intensity of the exercise. Progressive overload is essential for muscle hypertrophy, as it continuously challenges the muscles to adapt and grow stronger.

Applying Progressive Overload to Strict Curls

To build bigger and stronger biceps with strict curls, it’s crucial to apply the principle of progressive overload. Here’s how you can do it:

Increase the Weight

One of the most straightforward ways to implement progressive overload is by increasing the weight you lift over time. Start with a weight that allows you to complete 8–12 repetitions with strict form. Once you can perform 12 reps comfortably, increase the weight by 2.5–5 kg and reduce the reps back to 8. This cycle ensures that your biceps are continuously challenged, leading to muscle growth.

Scientific Insight: A study published in the Journal of Strength and Conditioning Research found that individuals who increased the weight lifted in their training program experienced greater muscle hypertrophy compared to those who maintained a constant weight (Schoenfeld et al., 2016).

Increase the Repetitions

Another method to apply progressive overload is by increasing the number of repetitions you perform. This is particularly useful when you reach a plateau in your strength gains. By increasing the volume of work (total repetitions), you enhance the stimulus for muscle growth.

Practical Tip: If you typically perform 8–10 reps, try increasing to 12–15 reps for a few weeks before returning to heavier weights. This variation in training volume can prevent plateaus and keep your muscles responding positively to the stimulus.

Control the Tempo

The tempo, or speed at which you perform each repetition, can significantly impact muscle growth. Slowing down the eccentric (lowering) phase of the curl increases the time under tension, which has been shown to promote muscle hypertrophy (Schoenfeld et al., 2015). For strict curls, try lowering the weight over 3–4 seconds while maintaining a strict form. This technique increases the difficulty of the exercise without the need to add more weight, making it an effective way to overload the biceps.

Progressive Overload Summary

By consistently applying progressive overload to your strict curl routine through increased weight, repetitions, or tempo control, you can ensure continuous growth and strength development in your biceps. Remember, the key is gradual progression and maintaining strict form to isolate the biceps effectively.

2. Utilising Variations of Strict Curls

Why Variations Matter

Incorporating different variations of strict curls into your workout routine can target the biceps from various angles, stimulate different muscle fibres, and prevent adaptation. Muscle adaptation occurs when your muscles become accustomed to a specific exercise, leading to diminished returns in strength and hypertrophy. By varying your exercises, you can keep your muscles guessing and growing.

Effective Variations of Strict Curls

EZ Bar Strict Curls

The EZ bar allows for a more natural grip position, reducing the strain on the wrists while still effectively targeting the biceps. This variation is particularly beneficial for those with wrist or elbow issues, as it places less stress on these joints compared to a straight barbell.

Scientific Insight: A study published in the Journal of Applied Biomechanics demonstrated that the EZ bar curl can reduce wrist and elbow discomfort while maintaining similar muscle activation levels as the straight barbell curl (Signorile et al., 2002).

Dumbbell Strict Curls

Dumbbell strict curls allow for unilateral training, meaning each arm works independently. This can help correct any muscle imbalances between the arms and ensure balanced muscle development. Additionally, dumbbells provide a greater range of motion, which can lead to more comprehensive biceps activation.

Practical Tip: To perform dumbbell strict curls, stand with your back against a wall, hold a dumbbell in each hand, and curl one arm at a time or both simultaneously. Ensure your elbows remain locked at your sides, and focus on squeezing the biceps at the top of each curl.

Seated Strict Curls

Seated strict curls eliminate the involvement of the lower body and further isolate the biceps. By sitting down and using a bench with back support, you reduce the potential for any body sway or momentum, making the exercise even more challenging for the biceps.

Scientific Insight: Research indicates that seated variations of curls can lead to increased muscle activation in the biceps compared to standing variations due to the reduced involvement of stabilising muscles (Youdas et al., 2010).

Incorporating Variations into Your Routine

To maximise the benefits of strict curls, it’s essential to incorporate different variations into your workout routine. You can alternate between these variations in different workouts or even within the same session. For example, you might start with EZ bar strict curls, move on to dumbbell strict curls, and finish with seated strict curls. This approach ensures comprehensive muscle activation and prevents plateaus.

3. Optimising Your Workout Structure with Strict Curls

The Importance of Workout Structure

The structure of your workout plays a significant role in the effectiveness of your training programme. Factors such as exercise order, rest periods, and frequency can all influence your results. When it comes to building bigger and stronger biceps with strict curls, optimising your workout structure is key.

Effective Workout Structure Tips

Exercise Order

The order in which you perform exercises can impact your performance and results. For biceps training, it’s generally recommended to start with strict curls early in your workout when your muscles are fresh and can generate maximum force. This ensures that your biceps receive the greatest stimulus for growth.

Scientific Insight: A study published in the European Journal of Applied Physiology found that performing isolation exercises (like curls) before compound exercises led to greater muscle activation in the target muscles (Gentil et al., 2007).

Rest Periods

Rest periods between sets play a crucial role in muscle recovery and performance. For hypertrophy-focused training, rest periods of 60–90 seconds between sets are generally recommended. This duration allows sufficient recovery while maintaining a high level of muscle fatigue, which is necessary for growth.

Practical Tip: To optimise your rest periods, consider using a timer or stopwatch to ensure you’re not resting for too long or too short a time. Consistency in rest periods helps maintain workout intensity and improves overall results.

Training Frequency

Training frequency refers to how often you work out a particular muscle group. For optimal biceps growth, it’s recommended to train the biceps 2–3 times per week, ensuring sufficient recovery between sessions. This frequency allows for adequate stimulus and recovery, leading to sustained growth over time.

Scientific Insight: Research published in the Journal of Sports Science and Medicine suggests that training a muscle group twice per week is more effective for hypertrophy compared to once per week (Schoenfeld et al., 2016). This approach allows for more frequent stimulation of the muscles, leading to better long-term results.

Example Workout Routine

Here’s an example of how you can structure your biceps workout to include strict curls effectively:

Workout A:

• EZ Bar Strict Curls: 4 sets of 8–12 reps
• Seated Dumbbell Strict Curls: 3 sets of 10–15 reps
• Hammer Curls: 3 sets of 10–12 reps

Workout B:

• Barbell Strict Curls: 4 sets of 6–10 reps
• Seated Strict Curls: 3 sets of 10–12 reps
• Concentration Curls: 3 sets of 12–15 reps

Alternate between Workout A and Workout B throughout the week, ensuring at least one rest day between biceps-focused sessions.

Conclusion

Strict curls are a highly effective exercise for building bigger and stronger biceps, provided they are executed with proper form and incorporated into a well-structured workout routine. By implementing progressive overload, utilising variations of strict curls, and optimising your workout structure, you can maximise your biceps development and achieve your strength goals. Remember, consistency and gradual progression are key to long-term success.
