What to avoid
The materials we leave out of the picks, why, and where to look instead.
Picks are not paid placements. We may earn a commission on some links.
1. PVC and vinyl mats and dumbbells
PVC may contain phthalates. A vinyl-dipped dumbbell is iron inside a plastic skin. Instead: mats and rollers.
2. TPE, EVA and PU foam mats and rollers
Plastic foams. They wear down with use, and the softness is the plastic. Instead: mats and rollers.
3. Neoprene or rubber-coated hex dumbbells, and urethane plates
The coating is a synthetic skin over the iron. Bare or stainless steel and cast iron have nothing to shed. Instead: weights and bars.
4. Recycled-tire (SBR) flooring indoors
SBR flooring smells and gives off VOCs, and a floor is the biggest surface in the room. Instead: flooring.
5. Polyester and nylon microfiber towels
Microfiber is plastic fiber, and towels are washed often. Instead: towels, straps and belts.
6. Plastic bottles, and plastic lids that touch the water
“BPA-free” can still mean plastic. It names one chemical that is absent, not what the bottle is made of. Instead: water bottles.
7. “Eco” or “natural” claims with no named materials or certification
A claim that names no material and no certifier cannot be checked. We skip those products.
8. Solar-meter irradiance headlines on red light panels
A solar meter overstates red light output by about 2.2 to 2.5 times, per Mito's own lab comparison. Rouge lists 164 (solar) beside 90 (spectrometer) at the same 6 in. Instead: red light therapy. Sources: mitoredlight.com, rouge.care.
9. “Zero EMF” badges with no named tester
PlatinumLED BIOMAX PRO, Vital, Hooga and EMR-TEK make the claim without saying who measured it. Hooga's PRO1500 claims “EMF Zero” and measured 0.16 uT at 6 in (and 86 mW/cm2 average against a claimed 189). Instead: red light therapy. Sources: platinumtherapylights.com, vitalredlight.com, lighttherapyinsiders.com.
10. “FDA-registered”, “FDA-Cleared Technology” or “FDA Class II” with no 510(k) number
Used without a 510(k) number, or next to a “not evaluated by FDA” disclaimer (Vital, RLT Home, Lumebox, Mito). Clearance or registration covers safety and equivalence, not results. Instead: red light therapy. Sources: vitalredlight.com, thelumebox.com.
11. Wattage in a red light panel's name
“750W” or “1500W” is rated LED power, not light output. The Hooga PRO750 draws 272 W. Instead: red light therapy. Source: hoogahealth.com.
12. Irradiance ranges with no distance
Figures like “150-210 mW/cm2” with no distance, or “1,400 mW/cm2 at panel face”, cannot be compared with a reading at a stated distance. Instead: red light therapy. Source: emr-tek.com.
13. Red light test data presented as independent
Outliyr and Light Therapy Insiders earn commissions and often get free units. Their data is still better than brand claims, but it should be disclosed. Our cards say when a figure comes from them. Instead: red light therapy. Sources: outliyr.com, lighttherapyinsiders.com.
14. Greatmats FlexeCork “cork” tiles
The seller calls them “more rubber than cork”, and the rubber is 75% recycled truck tire. Instead: flooring. Source: greatmats.com.
15. Calling Marmoleum “FloorScore certified”
Forbo's 2026 FloorScore certificate covers its adhesives only, not Marmoleum. Instead: Marmoleum Click Cinch Loc Seal (linoleum). Source: cdn.scscertified.com.
16. Expired FloorScore certificates on seller sites
Seller pages for Ecore (on Greatmats), Hero Flooring and nora have shown FloorScore certificates that had expired. Check the date on the certificate. Instead: flooring. Source: greatmats.com.
17. Stall mats sold as “no overwhelming rubber odors”
Horse stall mats are recycled tire (SBR) rubber. New ones smell strongly of tire, can off-gas VOCs, and carry no FloorScore or GREENGUARD certificate. The odor line is the seller's own claim. If you use them anyway, air them outdoors for weeks, wash them, and keep them out of living spaces. Instead: Rogue Deadlift Platform + Radiata Pine Wood Insert Set. Sources: agrifeedpetsupply.com, garagegymreviews.com, garagegympro.com.
18. Cheap “cork” mats that are a cork veneer on TPE foam
The cork is a thin top layer over plastic foam. Instead: mats and rollers. Source: yogadesignlab.com.
19. “Poly-Manila”, “Polyhemp” and “synthetic hemp” battle ropes
Plastic lookalikes of manila that shed microfibers. Some polyester ropes even carry a “Natural Fiber” badge. Instead: Conditioning Rope, 50 ft Power Rope (manila). Sources: rope.com, polyropes.eu, skroutz.eu.
20. Rogue's standard Battle Rope
Poly dacron rope with PVC handles. Rogue's manila Conditioning Rope is the plant-fiber version. Instead: Conditioning Rope, 50 ft Power Rope (manila). Source: roguefitness.com.
21. “Hemp Plastic” Indian clubs
Revolution Clubs sells them next to its oak clubs. They are plastic composite. Instead: 2 lb American Oak Indian Clubs (pair). Source: revolutionclubs.net.
22. GORUCK clone storefronts
Copies of GORUCK's store run on .it.com domains. Buy only on goruck.com. Instead: GR1 USA Heritage Waxed Canvas ruck (21 L / 26 L). Source: example clone domain: goruckus.it.com (not linked).
23. Fluid Film sold as “non-toxic, natural”
It is wool wax plus refined petroleum oils, and it is not biodegradable. Instead: Walrus Oil Knife Oil (bar wipe). Source: theruststore.com.
24. “RAW” equipment that is coated
The Tiguar “RAW” kettlebell is powder-coated, and Musclesquad “raw” plates are painted. Instead: Rogue Loadable Kettlebell (raw steel). Sources: physioparts.co.uk, musclesquad.com.
25. “Stainless” cold plunges with plastic interiors
Some plunges sold as stainless still have plastic inside, such as the Dundalk Polar Plunge. Instead: recovery and sauna. Source: topture.com.
26. Hardware-store boiled linseed oil
Brands such as Sunnyside and Klean-Strip add cobalt or manganese driers plus mineral spirits. Instead: gear care and chalk. Source: sunnysidecorp.com.
27. Minwax “tung oil finish”
Solvent-carried, with the tung oil content undisclosed. Instead: Pure Tung Oil (Chinawood), 100%. Source: minwax.com.
