What Is an Additional Insured? A Plain-English Guide for Fitness Pros

An additional insured is a person or business you add to your liability policy so they get protection if they get pulled into a claim caused by your work. Gyms that rent you space, landlords, apartment buildings, schools and corporate clients ask for it because they don’t want to pay for your mistakes. Adding them is usually quick and affordable. For a lot of fitness work, it’s the price of entry.

Below: what the request means, what it does and doesn’t do, the contract wording you’ll see, and how to handle it without holding up a client or a lease.

What is an additional insured?

An additional insured is a person or organization added to your liability policy, through a written change called an endorsement, who gets coverage for claims that arise out of your work. They share your policy limits. They don’t own the policy, don’t pay the premium, and usually aren’t covered for their own separate mistakes.

You are the “named insured,” the person or business that bought the policy. The other party rides along for claims connected to what you do.

Here’s how it plays out. An independent trainer rents floor time at a gym. A client drops a kettlebell on her foot during a session and sues both the trainer and the gym. If the gym was added to the trainer’s general liability policy (the coverage for injuries and property damage to other people), the trainer’s insurer can defend the gym for that claim too. Depending on the wording, the gym may never need to call its own insurer.

Who asks fitness pros and studios to add them?

Almost anyone who lets you work on their property or under their name. The most common requests come from:

• Gyms that rent space to independent trainers. Your client gets hurt in their building, so they want your policy to respond first.
• Commercial landlords. Most studio leases have an insurance section that requires it.
• Apartment, condo and HOA gyms. Building managers want a certificate before you train a single resident.
• Schools, colleges and rec centers. Especially for youth programs and facility rentals.
• Event hosts. Pop-up classes, charity workouts, races and competitions.
• Corporate clients. On-site wellness classes often come with a vendor contract and very specific wording.
• A parent company or headquarters. Licensed and franchised studios often must add the brand owner.

If you train independently, expect this request often. If you own a studio, expect it from your landlord and from any partner who hosts your classes.

What does an additional insured endorsement do?

The endorsement is the piece of paper that actually grants the coverage. Everything else is proof or promises. Once it’s attached to your policy, the other party can ask your insurer to defend them and pay covered damages for claims tied to your operations.

What it usually covers

• Bodily injury claims from your clients or class members that name the other party too
• Property damage you cause on their premises
• Legal defense costs for the other party on covered claims, which can matter more than the payout itself
• Claims where the other party is blamed only because your work happened on their property (called vicarious liability)

What it usually doesn’t cover

• The other party’s own independent negligence, like a broken stair the landlord never fixed. This depends on the policy wording and state law.
• Their building, their equipment, or their property in general
• Injuries to their own employees
• Claims that have nothing to do with your work
• Professional liability claims, in many cases. Many professional liability policies (the coverage for claims that your coaching or advice caused harm) offer additional insured status narrowly or not at all.

Read the wording before you promise anything. There are real situations where additional insured status did not protect the party that asked for it, because the claim fell outside what the endorsement covered.

One more thing: the other party shares your limits. Your limit is the most the policy pays for a claim. If a large claim names both of you, the settlement or judgment for both of you comes out of the same limit.

Certificate holder vs additional insured: what’s the difference?

People mix these up constantly, and it matters. A certificate of insurance (often called a COI) is a one-page summary that proves you have coverage. The certificate holder is just the party that receives that proof. Being a certificate holder gives them no coverage at all.

If a gym only wants proof you’re insured, list them as certificate holder. If their contract asks to be added to your policy, they need the endorsement.

Additional insured on certificate of insurance: what the paperwork looks like

The standard certificate form has a box for the certificate holder’s name and address, a column that marks which policies include added parties, and a description box where special wording goes. That’s where you’ll see lines like “Certificate holder is included as additional insured with respect to general liability, primary and noncontributory, per written contract.”

Know this: the certificate itself usually says it confers no rights and does not change the policy. The endorsement does the real work. Showing the other party on the certificate is a summary, not the coverage. If a contract requires it, ask your agent for a copy of the endorsement to send along with the certificate.

Blanket additional insured vs scheduled: which do you need?

There are two ways an insurer adds people to your policy.

Scheduled. Each party is named, one by one, on an endorsement. Every new gym or building means another policy change and another wait.

Blanket. The policy automatically includes anyone you agreed in a written contract to add, as long as the contract was signed before the incident. No new endorsement for each party. Your agent just issues a certificate.

If you train in more than one building, or your studio works with several partners, get a blanket endorsement. It saves time, and it closes the gap where a client gets hurt before a scheduled endorsement was processed. Just make sure the contract or written agreement exists and is signed before work starts, because a handshake usually doesn’t trigger blanket coverage.

What does primary and noncontributory mean?

You’ll see this phrase in leases and corporate contracts. It has two parts.

• Primary means your policy pays first, before the other party’s own insurance.
• Noncontributory means your insurer won’t ask the other party’s insurer to chip in.

Together, they keep the claim on your policy and off theirs. Many policies can be written this way, but it has to be in the endorsement, not just typed on the certificate.

A third request often rides along: a waiver of subrogation. Subrogation is your insurer’s right to sue someone else to recover what it paid. A waiver gives up that right against the other party. Landlords and corporate clients ask for it often, and it usually needs its own endorsement.

Landlord additional insured requirements in a lease

If you’re opening or renewing a studio, the lease will almost always require this endorsement. The usual list:

• The landlord (and often the property manager and lender) added on your general liability
• Primary and noncontributory wording
• A waiver of subrogation
• Minimum limits for general liability and sometimes an umbrella policy
• Notice to the landlord if your policy is canceled

Insurers often use a specific endorsement for this called “managers or lessors of premises.” Send the insurance section of the lease to your agent before you sign, not after. Some lease language asks for things your policy can’t provide, and it’s easier to negotiate before the ink dries.

Watch the indemnification clause too. Indemnification is a contract promise to pay for someone else’s losses (often paired with “hold harmless”). A clause that makes you cover the landlord’s own negligence can leave you on the hook for losses your policy won’t pay.

How to handle the request: step by step

1. Get the request in writing. An email or the contract section is enough. You need to see the exact wording.
2. Collect the exact legal name and address. The name on the certificate should match the contract.
3. Flag special wording. Look for primary and noncontributory, waiver of subrogation, notice of cancellation, and required limits.
4. Check how your policy handles it. If you have a blanket endorsement, you may only need a certificate. If not, your agent adds a scheduled endorsement.
5. Send everything to your agent. Ask for the certificate and, if the contract requires it, a copy of the endorsement.
6. Keep a file and renew it. Certificates show your policy dates. When you renew, send updated certificates before anyone has to ask.

Mistakes trainers and studio owners make

• Promising wording in a contract before checking that the policy can provide it
• Treating a certificate as coverage, when only the endorsement gives it
• Signing an indemnification clause that covers the other party’s own negligence
• Letting the policy lapse, which leaves every party on your certificates unprotected
• Adding parties who never asked, since every one of them shares your limits
• Training in a new building before the certificate is issued

Trainer and studio insurance: getting added parties right

Your policy has to do two things. It has to cover your own work, and it has to make adding other parties fast and clean. If you train independently, your personal trainer insurance should cover every place you work, including client homes, parks, apartment gyms and online sessions, and should let you add gyms and buildings quickly, ideally through a blanket endorsement.

If you own a gym or studio, your landlord, partners and event hosts will all want proof. That means general liability that meets your lease, professional liability for your coaches, and the endorsements your contracts require.

NEXO Insurance Services has insured over 20,000 fitness professionals since 2005. NEXO covers independent personal trainers and instructors through Alternative Balance, which issues same-day certificates of insurance, so a building manager’s request never holds up a new client. For studios and facilities, see NEXO’s guide to gym and fitness studio insurance and ask how your policy handles additional parties before you sign your next lease.

The bottom line on additional insured status

An additional insured gets coverage under your policy for claims tied to your work, and the endorsement, not the certificate, is what creates it. Get every request in writing, check the wording with your agent, and use a blanket endorsement if you work in many places. Handle it right and the request takes minutes instead of holding up a lease or a client.

Additional insured FAQ

Does adding someone to my policy cost extra? It depends on the policy. Some include blanket status at no extra charge, while others charge for each scheduled name, so ask NEXO Insurance Services or your agent how your policy handles it.

Is an additional insured covered for their own negligence? Usually not. Most endorsements cover the other party only for claims arising out of your work, and the exact limits depend on the wording and state law.

How long does it take to add a gym or landlord to my policy? With a blanket endorsement it can take minutes, since your agent only issues a certificate. NEXO Insurance Services issues same-day certificates for independent trainers and instructors through Alternative Balance.

What is the difference between a named insured and an additional insured? The named insured buys and controls the policy. The added party gets narrower protection, only for claims connected to the named insured’s work.

Can a person be added to my policy, or only a business? Either one. A landlord, a property manager, a gym owner or a corporate client can all be added if your policy allows it.

Will the other party be told if my policy is canceled? Not automatically. Some policies can add a notice of cancellation endorsement, so ask your agent if a contract requires it.

Do I need to add the gym where I rent space? If the gym asks, yes. Many gyms that rent space to independent trainers require it before your first session, so get it done before you start.
