When it comes to cutting, bodybuilders face a challenging balance: losing fat while preserving as much lean muscle mass as possible. Traditional cutting strategies involve a combination of calorie deficits, high-protein diets, and intense training regimens. However, one emerging tool that is gaining traction in the fitness community is red light therapy (RLT). This non-invasive, science-backed treatment can enhance recovery, boost fat loss, and support overall performance, making it a valuable asset for bodybuilders during their cutting phase.
What Is Red Light Therapy?
Red light therapy (also known as photobiomodulation) uses low-wavelength red and near-infrared light to penetrate the skin and stimulate cellular processes. These wavelengths interact with mitochondria in cells, enhancing energy production, reducing inflammation, and promoting tissue repair.

How Red Light Therapy Supports Cutting
Here’s how red light therapy can be a game-changer for bodybuilders looking to shed fat while maintaining muscle:
1. Enhances Fat Loss
Red light therapy has been shown to help with fat loss by stimulating mitochondria to produce more ATP (adenosine triphosphate), which increases cellular metabolism. Studies suggest that RLT can encourage the breakdown of fat cells (lipolysis) and improve blood circulation, helping the body more efficiently mobilize and utilize stored fat for energy.
2. Preserves Muscle Mass
One of the biggest concerns during a cutting phase is muscle catabolism. RLT helps by reducing oxidative stress and inflammation, which can contribute to muscle breakdown. Additionally, it supports protein synthesis, ensuring that the hard-earned muscle mass is maintained despite being in a calorie deficit.
3. Accelerates Recovery and Reduces Inflammation
Cutting often involves high-intensity workouts, which can lead to muscle soreness and inflammation. Red light therapy helps by boosting circulation and reducing oxidative stress, allowing muscles to recover faster. This means bodybuilders can train harder and more frequently without compromising performance.
4. Improves Sleep Quality
Quality sleep is crucial during a cutting phase, as it directly impacts hormone regulation, muscle recovery, and fat loss. RLT has been shown to regulate circadian rhythms and increase melatonin production, promoting deeper and more restful sleep, which is essential for optimal recovery.
5. Supports Skin Health and Appearance
During a cut, rapid fat loss can sometimes lead to loose skin or reduced skin elasticity. Red light therapy promotes collagen production, which helps maintain skin firmness and reduces the appearance of stretch marks.
How to Use Red Light Therapy During a Cut
For best results, bodybuilders should aim to use red light therapy for about 10–20 minutes per session, 3–5 times per week. Sessions can be done before or after workouts, or even in the evening to aid with relaxation and sleep. Using a high-quality, high power, full-body red light therapy bed ensures maximum coverage and effectiveness.
Final Thoughts
Red light therapy is a powerful, science-backed tool that can support fat loss, muscle preservation, and overall recovery during a cutting phase. By integrating RLT into their routine, bodybuilders can optimize their results, improve recovery, and maintain peak performance. If you're looking for an edge in your next cut, red light therapy might be the missing piece in your regimen.
