Strength Training for Osteoarthritis in East Finchley, London (N2)
Strength training for osteoarthritis at Ultimate Strength is one-to-one supervised work on MedX and Nautilus machines, in a private studio in East Finchley, North London (N2). The point is not the joint itself but the muscles around it - a stronger quadriceps takes load off an arthritic knee, a stronger glute and hip-abductor pattern takes load off an arthritic hip. The protocol behind every session is High Intensity Training (HIT) - a slow, controlled, one-to-one strength protocol, distinct from HIIT (High Intensity Interval Training).
What we mean by strength training for arthritis
We work with clients living with osteoarthritis - the wear-and-tear kind, most commonly in the knee and hip. Sessions are one to one, by appointment, on machines that load the muscles around the affected joint in a controlled range.
We are not making a cartilage claim. Strength training does not regenerate cartilage and we will not say it does. What it can do is build the muscles that load and stabilise the joint, so the joint itself carries less of the work in everyday life. A stronger quadriceps and hamstring share the load that would otherwise pass through an arthritic knee. A stronger gluteus medius and hip-abductor pattern shares the load that would otherwise pass through an arthritic hip. Many of our clients report less day-to-day pain, more confidence on stairs, easier walking, and an easier time getting up off the floor.
We are not a clinic. We do not diagnose, prescribe or replace any care your GP, rheumatologist, orthopaedic consultant or physiotherapist is providing. A meaningful number of our clients arrive on a recommendation from one of those professionals. We are happy to liaise with them, and to share session records on request.
A short note on rheumatoid arthritis. RA is a different condition - inflammatory and systemic, not wear-and-tear - and acute inflammatory flares are not suitable for loaded training. Anyone with RA should have their rheumatologist's input before starting, and we will ask for written sign-off.

Machine-based loading suits an arthritic joint
The reason we work on machines, not free weights, is most obvious in clients with osteoarthritis.
The joint moves in a fixed path. The range is set by the coach and capped where it needs to be capped. There is no impact, no jolt, and no balancing under load - the seat, pad and restraint hold you in position, so the muscle does the work and the joint is not asked to stabilise the body at the same time. The cadence is slow in both directions, so the joint is loaded smoothly rather than spiked.
For a knee or hip that is already irritable, that combination - controlled range, no impact, no balancing demand, slow loading - is the difference between training the muscle around the joint and aggravating the joint itself.
Why slow, supervised loading helps arthritic joints
Three reasons, in plain terms.
- Stronger surrounding muscle, less load through the joint. When the muscles around an arthritic knee or hip get stronger, they absorb more of the force of walking, climbing stairs and standing up. The joint itself carries less. For many of our clients this shows up as less day-to-day pain, even though the underlying joint has not changed.
- Controlled speed, no impact spikes. A ten-second lift and ten-second lower removes the snap and jolt that arthritic joints handle badly. The joint is never asked to absorb a sudden load.
- Small written increments, no surprises. Weights move in small increments, recorded on paper, calibrated to the previous session. The joint is never asked to do more than it has already shown it can handle. You build into the work, you do not test into it.
A 30 to 45-minute session a week is, for most clients, enough. Recovery happens between visits.
“We are not trying to change the joint. We are trying to change what the joint has to carry. Stronger muscle around an arthritic knee or hip is the most reliable lever we have.”
Yoram Sher · Director and head coach
Where we focus, by joint
Knee and hip are by far the most common presentations, so most of the work on the floor sits there.
Knee osteoarthritis
The two main levers are the quadriceps and the hamstring. We work the Nautilus Seated Leg Extension and Nautilus Prone Leg Curl with careful range setting, and use the Nautilus Leg Press for compound loading of the quadriceps, glutes and hamstrings together, in a position that supports the back and pelvis. Where a knee will not tolerate full extension, we cap the range. Where one leg is significantly stronger than the other, we will often work them separately so the weaker side is not carried by the stronger.
Hip osteoarthritis
The pattern here centres on the gluteus medius, the hip-abductor pattern, the hamstrings and the glutes. The MedX Core Lumbar Strength and Core Torso Rotation machines also feature, because hip clients almost always need the trunk and pelvis loaded alongside. Single-side work is common - one hip is usually worse than the other - and we frame the work around the things our clients say they want to do without pain or hesitation: walking on uneven ground, going up and down stairs, getting in and out of cars, standing up from a low chair.
Other joints
Shoulder, hand, foot and other osteoarthritic presentations come up less often, but they come up. We can adapt - capping range, choosing machines that load the muscle without rotating the affected joint, working the opposite side and the surrounding chain. If you have arthritis in a less common joint, the conversation belongs in a phone call rather than a paragraph here.
Who this is for
Most of the people who come to Ultimate Strength with osteoarthritis fall into one or more of these groups.
- Knee osteoarthritis with day-to-day pain, stiffness on stairs, or weakness in the quadriceps that has built up while you have been avoiding load.
- Hip osteoarthritis with pain on walking, difficulty with stairs, or a wider weakening of the gluteus and hip-abductor pattern.
- Cleared for resistance training by your consultant, post-flare, post-injection or post-conservative-treatment, and looking for supervised progression.
- Awaiting or recovering from a joint replacement where strengthening the surrounding muscle before or after surgery is part of the plan, with written sign-off from the surgical team.
- RA in a settled, non-flare phase with your rheumatologist's input and written sign-off.
Who this is not for, at least not yet
We are honest about this on the phone and at a first visit.
- If you are in an acute inflammatory flare - RA flare, post-injury swelling, a hot or visibly swollen joint - resistance training is not the right next step. See your rheumatologist, GP or physiotherapist first.
- If your consultant has advised against resistance training at this point in your care, we will wait for that to change.
- If you are awaiting a joint replacement and have been told to rest the joint until surgery, we will wait for the surgical team's sign-off before loading.
- If you have a related condition that complicates loading (uncontrolled inflammatory disease, recent fracture, unstable cardiac status), we will ask for written sign-off from the relevant doctor before starting.
An introduction session is the easiest way to find out which side of this line you sit on.
“In spite of an ongoing back problem for the past thirty years, strength training has benefitted me enormously. Best of all, it is a form of training that has no age barrier, and can be continued in later life, keeping us toned and strong.”
Janet Wise · long-standing client
How a first session works
It takes about forty minutes.
- We walk the floor and look at each machine, with the knee and hip stations in particular.
- You talk through your arthritis history, any imaging or letters you want to share, any medication you take regularly, and any restrictions your consultant or physiotherapist has set.
- You try one or two calibration sets on the most relevant machines - typically the leg extension and leg curl for a knee, or the leg press and a hip-abductor pattern for a hip. The starting weights are deliberately conservative. We are calibrating, not testing.
- We agree whether a programme makes sense. There is no commitment to continue, and we will say so plainly if we think a different setting is the better fit for you right now.
If you do continue, sessions are by appointment, one to one, with the same coach every visit. We keep a written log of every weight, set and note, and you are welcome to a copy at any time, including to share with your GP, physiotherapist, rheumatologist or consultant.
