Knee Strengthening Exercises at Home: 9 Moves for Stronger Knees
Nine knee strengthening exercises you can do at home with no equipment or a pair of dumbbells, plus sets, reps and how to progress safely if your knees hurt.

Plantar fasciitis is the reason a surprising number of people limp to the bathroom every morning and feel fine again by lunchtime. The plantar fascia is a thick band of connective tissue running from your heel bone to the base of your toes, holding up the arch, and when it gets irritated it tightens overnight and complains loudly at the first weight you put through it. Then it warms up, you forget about it, and the cycle repeats tomorrow.
The good news is that this responds to exercise better than almost any other stubborn foot problem, and there is decent trial evidence behind the specific stretch that works best. The bad news is the timescale. This is a two-month project at minimum, and most of the people who tell you plantar fasciitis exercises did not work for them stopped somewhere around week three.
Most people are told to stretch their calf. That helps, but a randomised trial run on 82 patients with chronic proximal plantar fasciitis of more than ten months compared a plantar fascia-specific stretching protocol against an Achilles tendon stretching protocol and found substantial differences in favour of the plantar fascia group at eight weeks (DiGiovanni et al., two-year follow-up). The gap was largest on the measure people care about most: pain with the first steps in the morning.
How to do it. Sit down. Cross the affected leg over the opposite knee so the sole faces upward. Grab the base of your toes with the hand on the same side and pull them back towards your shin until you feel a firm stretch through the arch. Run the thumb of your other hand along the fascia; it should feel taut, like a guitar string. Hold ten seconds, release, repeat ten times. Do the whole thing three times a day, and do the first set before you get out of bed in the morning.
That last detail matters more than it sounds. Stretching the fascia before you load it is what stops the tearing-and-healing cycle that causes the morning pain in the first place.
Before you get out of bed
Keep this guide, or a note on your phone, next to the bed. The single highest-value minute of the day is the one spent stretching the fascia before your heel takes any weight. Everything else on this page is secondary to that.
Start with the first four. Add the strength work once the morning pain has dropped noticeably, usually somewhere around week three.
Stretches three times a day, every day. Strength work every other day, so three or four sessions a week. Nothing here takes more than ten minutes, which is the point: the protocol only works if you can sustain it for two months without rearranging your life around it.
Track the morning pain rather than daytime pain, because that is the measure that moves first and moves most reliably. If it has not budged at all after six weeks of genuinely consistent work, that is the point to see a physio rather than to double the reps.
Footwear does a lot of the heavy lifting. Walking barefoot on tile or laminate is the most common thing that keeps this problem alive in people who are otherwise doing everything right, so keep supportive shoes or a decent pair of slippers by the bed and wear them in the house. A cushioned insole is worth trying; the evidence for expensive custom orthotics over cheap off-the-shelf ones is not strong.
Load management matters as much as it does with any overuse injury. If running triggered it, running volume needs to come down until the fascia catches up. Cycling, rowing and swimming keep your fitness intact in the meantime, and our best exercise bike UK guide covers low-impact options for home. The NHS advice on plantar fasciitis is broadly the same: keep active, avoid the specific things that aggravate it, and give it time (NHS plantar fasciitis guidance).
Bodyweight is the factor nobody enjoys discussing, but every kilogram passes through the fascia several thousand times a day if you are on your feet. It is not the whole story and it is not a moral issue; it is simply one of the larger levers available.
Heel pain that has not improved at all after twelve weeks of consistent work, pain that is present constantly rather than worst in the morning, numbness or tingling into the foot, or pain following a specific injury all warrant proper assessment. Nerve entrapment, fat pad atrophy and calcaneal stress fractures all masquerade as plantar fasciitis, and they need different treatment.
The plantar fascia-specific stretch, done seated by pulling your toes back towards your shin with the affected leg crossed over the other knee. A randomised trial of 82 people with chronic heel pain found it beat an Achilles tendon stretching protocol at eight weeks, with the largest single difference showing up in pain on the first steps of the morning. Do it ten times, holding ten seconds each, three times a day.
Expect the first noticeable change in two to three weeks and meaningful improvement by eight weeks. Most people are substantially better within six months of consistent work, and the two-year follow-up on that same trial showed continued improvement across both groups. The failure mode is not the exercises, it is stopping them after ten days because nothing has changed yet.
Both, and strength is the half people skip. Stretching the plantar fascia and calf relieves symptoms; loading the calf and foot builds the capacity that stops the problem returning. Heavy, slow calf raises with the toes propped on a rolled towel are the standard progression once the acute pain has settled.
It helps with symptoms, particularly first thing in the morning, and a frozen water bottle adds a useful cooling effect. It is a good warm-up before the real stretches rather than a treatment in itself. Two minutes per foot is plenty; grinding away for ten minutes on an already irritated fascia makes things worse.
Walking barefoot on hard floors, standing all day on concrete, flat unsupportive shoes, a sudden jump in running volume, and tight calves. Weight gain increases the load through the fascia with every step, which is why the condition is more common in people with a higher BMI and in jobs that involve long periods standing.
Yes, but change what you do. Cycling, swimming, rowing and upper body strength work all leave the fascia alone. Running, skipping, jumping and long walks on hard ground are the things to pull back on until the morning pain has gone. The NHS advises staying active while avoiding the specific activities that aggravate it.
