Making use of the fitness facilities at spa hotels in London could help older guests boost their health and wellbeing.
Alison Wyndham, physiotherapist and founder of the Wyndham Centres clinics, said exercise has considerable benefits for older people.
It can keep the joints moving, which is important for arthritis sufferers, and it helps to strengthen the muscles.
"The most important thing with arthritis is that you keep warm and you keep moving," she remarked.
Fitness activities can also encourage the production of endorphins in the body, which leads to a feeling of wellbeing.
"There is certainly evidence to show that exercise helps the memory in older people," Ms Wyndham added.
Older guests at The Montcalm can enjoy a range of activities in the hotel's fitness centre, including treadmills for brisk walking and fitness bikes for gentle cycling.
There is also an exercise pool and a spa pool featuring hundreds of hydrotherapy air jets, as well as a sauna, steam room and monsoon shower.
With the body taken care of, guests can boost their mental wellbeing with a luxurious spa treatment such as a massage or a facial.
Of course staying in the heart of London, there is plenty to do around the city.
Exploring the many tourist attractions on foot could be a great way for older people to keep fit and active on their break.
"Walking is probably the best exercise of all," Ms Wyndham insisted.
"If you have shoulder problems, you can bring in gentle neck and shoulder exercises and go through the motions of each movement."
The Montcalm is situated near Marble Arch on the edge of Hyde Park, where there are a number of interesting walking routes.
The park is home to the Serpentine Lake, the Diana Princes of Wales memorial fountain, the July 7th memorial and the famous Speaker's Corner.
