Everything we offer, and the why behind it.

A full walk-through of our services — physical therapy, contrast therapy, the sauna and plunge, and biometric testing — with links to the peer-reviewed studies each one is built on.

What we offer & why

Every session is a full sixty minutes, one-on-one with your therapist — no handing you off to an aide, no session clock dictated by a billing code. Because we're out-of-network, the length and shape of your care is a clinical decision, not a billing one. Every PT session also includes same-day access to the full contrast suite and the HydroMassage chair, with an InBody body-composition scan at intake and discharge to measure real progress — so the recovery work compounds the hands-on work.

Contrast therapy alternates heat and cold in cycles: sauna at 160–190°F, then a cold plunge at 40–52°F, repeated three to four times. Heat opens the blood vessels, cold constricts them, and moving between the two creates a vascular pumping rhythm — so a single session delivers the benefits of both heat and cold. Pooled trial data show contrast meaningfully reduces muscle soreness and strength loss versus simply resting, and heat and cold each carry their own evidence, which is why we built the suite around both.

Heat drives vasodilation, raising blood flow and tissue extensibility so the muscles are primed for manual therapy and movement. Beyond recovery, frequent sauna use carries one of the strongest longevity evidence bases of any passive modality — a 20-year study of 2,315 men linked 4–7 sessions a week to a 63% lower risk of sudden cardiac death and 40% lower all-cause mortality. Our three-tier bench lets you self-select your heat by where you sit.

The plunge triggers vasoconstriction, easing swelling after you've worked, along with a sharp catecholamine release. Recent network meta-analyses connect cold-water immersion to faster neuromuscular recovery, less soreness, and lower creatine-kinase; the clear-headed, alert feeling afterward is the widely reported downstream effect of that norepinephrine and dopamine surge. We run three plunges — 52°F for beginners and post-surgical clients, 46°F intermediate, 40°F advanced — so you start where it makes sense.

Your watch estimates; we measure. Consumer wearables can miss VO₂ Max by more than 10% depending on the device, and can't read resting metabolic rate at all. A PNOĒ breath test reads 23 markers directly from your breath, including VO₂ Max, resting metabolic rate, and biological age, then generates a personalized nutrition and training plan. It's $400 as a standalone assessment — and we credit the full amount toward membership if you join within 30 days.

Membership exists for the person who wants contrast therapy to become a routine, not an occasion — unlimited suite access and guest passes. Members also get access to wellness classes (mobility, gentle movement, and guided breathwork) led by local instructors at a member rate; classes are booked and paid per session. Membership is simply the best value if you're coming regularly; if you're not, day passes and à la carte testing are always open to you.

Getting started

NRTR is cash-pay and out-of-network — no billing codes deciding how long your session runs. We provide superbills so you can submit to your insurer for out-of-network reimbursement, which for many plans meaningfully reduces the effective cost.

Physical therapy sessions are generally eligible for HSA and FSA payment as qualified medical expenses. Contrast suite memberships are generally not HSA/FSA-eligible on their own; some plans accept a Letter of Medical Necessity from a physician. We'll provide documentation for any claim you submit.

We're opening at 65 Church Street in Montclair in spring 2027. Join the founding list and we'll keep you posted as opening approaches.

No. You can book physical therapy or biometric testing without a membership, and the contrast suite is available on day passes — $40 off-peak, $65 peak. Membership is simply the best value if the suite becomes part of your routine.

Your first visit

Swimwear is required throughout the wet suite. We provide towels, robes for the recovery lounge, day lockers, and showers stocked with products — bring yourself and a swimsuit; we handle the rest.

The suite is open-format and co-ed. Most members come alone and leave in the quiet, unhurried mood the room sets — not a scene, not a workout class.

The wet suite is open to members and guests 18 and older. Guests age 16–17 may enter accompanied by a parent or guardian, with a signed waiver on file.

Every plunge runs continuous filtration with ozone and UV treatment. Water chemistry is monitored and logged throughout the day, to the same public recreational bathing standard New Jersey applies to commercial pools — because it applies to us, and we'd hold ourselves to it anyway.

The practices

That's exactly why there are three. The 52°F plunge is an easy entry point, ideal for beginners and post-surgical clients; 46°F is intermediate; 40°F is the advanced reset. The sauna works the same way — a three-tier bench lets you self-select your heat by where you sit.

A typical round runs 10–20 minutes in the sauna, then one to three minutes in a cold plunge — most people repeat that three to four times. There's no single right protocol: our team helps you find a cadence that suits your goals and experience, and the suite is communal so you're never doing it alone.

Sixty minutes, one-on-one with your therapist, plus complimentary same-day access to the full contrast suite as part of your protocol, an InBody body-composition scan at intake and discharge, and use of the HydroMassage chair.

Because the evidence we build on — including the 20-year mortality data — is drawn from traditional Finnish saunas, not infrared. A Finnish sauna heats the air to 160–190°F, raising core temperature and creating the cardiovascular load behind those benefits, and it reaches the heat the contrast cycle depends on. Infrared runs cooler and warms you directly at lower air temperatures — pleasant, but a gentler, less-studied stimulus that can't drive the same response.

The recovery research we cite uses cold-water immersion, and water pulls heat from the body far faster and more evenly than cold air. A plunge cools the whole submerged body for the one to three minutes the protocol calls for, reaching tissue in a way a cryo chamber's brief surface chill doesn't — so it's the better-studied and more complete cold stimulus. Three graduated plunges let you start where it makes sense.

It's well tolerated by most healthy adults, but heat and cold extremes aren't right for every condition — pregnancy, certain cardiovascular conditions, and some medications warrant caution. We screen at intake and, when in doubt, ask you to clear it with your physician first. The research describes population-level effects, not a promise for any one person.

Membership & pricing

Standard membership is $250/mo for unlimited contrast suite access; Performance is $325/mo and adds quarterly metabolic assessments. Founding members lock in $225 and $300 respectively for their first year.

Yes. Standard members get two guest passes a month; founding members get five. Each guest can come in on your pass once a month — after that they're welcome any time on a day pass. It's a communal space by design, and we want you to share it.

Yes — straightforward terms, cash-pay clarity, and the freedom to pause. We aim to earn the month, every month, rather than lock you in.

Yes — members get access to wellness classes (mobility, gentle movement, and guided breathwork) led by local instructors, starting with a small schedule and scaling over time, capped small so the room stays personal. Classes are booked and paid per session; membership includes access and a member rate.

Visiting

65 Church Street, in the heart of downtown Montclair — a new mixed-use building, minutes from the Bay Street and Walnut Street stations, with on-site parking (ten dedicated and twenty public stalls).

We're open six days a week and closed Sundays. Exact hours will be listed ahead of opening; peak windows are mornings and early evenings on weekdays, and weekend mornings.

Yes — ten dedicated retail stalls plus twenty public stalls within the building, with direct access to the lobby.
