What Is Red Light Therapy At Crunch Fitness

How Red Light Therapy Actually Works at Crunch

Crunch Fitness locations have started rolling out red light therapy recovery pods and chairs over the last few years. They're usually sitting in a corner of the gym near the stretching or recovery area, sometimes right by the ice machines or foam rollers, sometimes in a semi-private nook depending on which location you hit up. The basic premise is straightforward: you sit or recline in front of panels that emit low-level wavelengths of red and near-infrared light, and the theory is that those photons get absorbed by your cells and help with recovery, inflammation reduction, and skin improvement. It's not a tanning bed, and it doesn't produce UV light. That's the first thing people confuse it with. Crunch typically uses devices from companies like RedLightHealth or similar providers who lease them to gym chains. The units are freestanding panels — usually two or three vertical light-emitting panels arranged around where you'd sit — with an adjustable height mechanism and a timer. A standard session runs 10 to 15 minutes per body region. You can do legs, back, or both arms and shoulders in one pass. Some of the newer pods enclose you more fully, almost like a tanning bed without the bulbs. The technical specs you'll see listed on the units are usually something like 660 nanometers for the red light and 850 nanometers for the near-infrared. The 660nm wavelength is more superficial, meaning it hits the skin and the layers just beneath it. The 850nm penetrates deeper into muscle and joint tissue. That's why people are generally using it for sore muscles after a workout rather than just for skin concerns, though both are valid applications.

Here's where it gets practical: I tried this at my local Crunch in Brooklyn after doing a heavy leg day, specifically targeting quads and hamstrings because I was running around 48 hours out from a competition and needed something between workouts that wasn't foam rolling or compression boots. The unit I used was the RedLightHealth Sola model — it's one of the bigger floor-standing ones, roughly seven feet tall, with panels you can angle toward different body regions. I set it for 12 minutes, sat in the chair, aimed it at my front and back quad, then flipped to the rear. Felt nothing. Absolutely nothing. No heat, no tingling, no sensation at all. That's actually normal and somewhat important to understand — this isn't a heating pad. If you're expecting warmth, you'll be disappointed. What I did notice over the next two days was slightly less stiffness when I hit my follow-up leg session compared to what would've normally been the case. Whether that's the red light doing something or just the placebo effect of spending 15 minutes sitting still after a workout is honestly impossible to say definitively. The research is mixed, and I'll get to that. But from a practical standpoint, it's free with your membership if your Crunch has the units, so there's no real downside to trying it unless you have a photosensitivity condition or are on medications that make you light-sensitive, in which case you should probably skip it or check with a doctor first. The main thing most people miss about using these units is positioning and distance. The closer you are, the more intensity you're getting, but the units are designed with a minimum safe distance built into their power output. Sitting too close won't burn you — these are medical-grade Class 1 or Class 2 lasers and LEDs, which means they're considered safe for unattended exposure — but you also don't want to just press your face against the panel for maximum exposure. The manufacturer guidelines usually suggest keeping about 12 to 18 inches between your skin and the light source for optimal penetration without overshooting the dose. Most Crunch locations don't post this, so you're mostly figuring it out yourself.

Another thing worth noting: the devices at Crunch are shared. You're sitting in a chair that dozens of other people have sat in, and while the units don't make direct skin contact beyond the light itself, there's a certain amount of personal boundary violation that comes with it. I always bring a small towel to drape over the chair surfaces that would contact my skin. It's not hygiene-critical in any dangerous way — the light itself doesn't transmit bacteria — but it makes it more comfortable from a psychological standpoint, and honestly, gyms are gross regardless of how many sanitizing wipes they hand out. Effectiveness depends heavily on what you're using it for. For muscle recovery after resistance training, the evidence is moderate but not overwhelming. A few studies show reduced delayed onset muscle soreness and faster return to performance markers, but the sample sizes tend to be small and the protocols vary wildly. For joint pain or inflammatory conditions, the data is thinner still. For skin quality — collagen production, wound healing, acne — there's somewhat more research backing it, but again, that's not why most gym-goers are sitting in these things. If you go into this expecting a miracle cure for everything, you'll leave frustrated. It's a recovery adjunct, not a treatment. The same way that ice baths and compression boots are adjuncts. Useful for some people in some contexts, not universally transformative. At Crunch specifically, since it's included in your membership and takes up maybe 15 minutes of your time, it's worth cycling through a few sessions here and there to see if you notice a difference. Track it simply: rate your soreness on a scale of one to ten the morning after a heavy session, with and without using the unit the night before, over the course of a month. That'll tell you more than any marketing brochure.

One edge case I ran into: I once used the unit right after a particularly brutal deadlift day when my lower back was genuinely tight and achy. I put the panel angled toward my lumbar region and ran a full 15-minute session. That night I slept fine, woke up the next morning feeling reasonably okay. But about an hour later, I developed a mild headache that lasted through the afternoon. I can't confirm it was from the red light — dehydration from the workout is a more likely culprit — but I've been cautious about using it on my upper body and head area since. The 850nm near-infrared does penetrate quite deeply, and while there's no evidence it's harmful to the brain, some people report sensitivity. If you notice headaches or anything unusual after a session, that's your sign to either shorten the duration or avoid that body region. The bottom line is that red light therapy at Crunch is what you make of it. It's accessible, it's free with your membership, it's not dangerous when used as directed, and it might help a little with recovery if you give it a fair shot. Don't expect it to replace foam rolling, sleep, or proper nutrition. Just treat it as one more tool in the recovery toolkit and move on with your day.
