Fitness editorial and product reviews

Breaking Muscle

Editorial reviews Free to read Visit Breaking Muscle ↗

Breaking Muscle is a credentialed editorial operation that discloses its affiliate model upfront, but its own disclaimer concedes financial ties to nearly every brand it ranks, and its best-of lists lack any published testing methodology to verify that hands-on evaluation drives the rankings.

What it's really for Drive affiliate-linked product purchases through SEO-optimized fitness content and best-of lists.

What our grade covers The grade on this page is about Home gym equipment, strength training gear, supplements, and fitness accessories, not everything the site does.

Medium Scoring Confidence Mostly sourced, but a detail or two still needs a primary source, so the grade could shift slightly.

Follow the money

Breaking Muscle's own affiliate-disclaimer page states it has "an affiliate relationship (either direct or through places like Amazon) with nearly every company whose products are reviewed" and generates commissions when readers purchase through review links. The site also receives free products from vendors.

What it costs you
Free to read The reviews are free to read.
How they make money
Affiliate commissions on product links (primarily Amazon and direct brand programs) plus free product receipt from reviewed brands.
What they do
Staff writers and certified coaches publish hands-on equipment reviews, supplement roundups, and best-of rankings for home gym gear, barbells, protein powders, and training accessories. Authors hold fitness certifications (ISSA-CPT, etc.) and the site discloses affiliate relationships near the top of review articles.
What to watch for
Best-of lists lack published testing protocols — no stated criteria weights, testing duration, or objective measurements. The site receives free products from the brands it ranks, and holds affiliate relationships with "nearly every company whose products are reviewed" per its own disclaimer, meaning the financial incentive runs toward recommending purchasable products rather than against them.

How the grade was reached

Independence · 30% weight 2 / 5

Does the site take money from the very entities it ranks? Pay-for-placement, vendor-funded data, and affiliate commissions all pull this down. The less the ranking can be bought, the higher the score.

Evidence basis · 30% weight 2 / 5

What is the ranking actually built on? Hands-on testing scores highest, then verified first-hand reviews, then opinion or popularity surveys and self-reported figures, then pay-to-rank, which scores lowest.

Method transparency · 20% weight 3 / 5

Is the methodology published, specific, and reproducible? Can a reader see how a given rank was reached, or is it a black box?

Conflict disclosure · 10% weight 3 / 5

Are commercial relationships, sponsorships, and affiliate arrangements disclosed clearly and near the rankings themselves, rather than buried?

Manipulation resistance · 10% weight 2 / 5

How hard is it to game? Controls against fake reviews, solicited reviews, and vendor gaming raise this; an open box anyone can stuff lowers it.
