And you don't have to be in the gym all day to see the benefits. Just 30 mins of brisk walking or similar exercise five times a week can help reduce the risk of breast cancer by as much as 25%, and bowel cancer by as much as 45%; it can slash the risk of ever developing dementia or having a stroke by as much as 30%. The chances of developing heart disease also fall by over 40%.

These extraordinary statistics come from a report launched mid February by the Academy of Medical Royal Colleges. The full report can be downloaded from the Academy of Medical Royal Colleges website.

Here's a few simple exercise routines that I recommend to clients. They're all easy and some of them are even fun!

• Walking is still one of the best exercises there is. You don't need any special equipment, it's practical (it gets you where you're going) and you'll feel the benefits on just 20 minutes a day
• Ever thought about getting a dog? According to the report, people who regularly walk a dog are 34% more likely to attain sufficient weekly physical activity than those who do not.
• Stairs are your friend - avoid taking the lift whenever possible; rest between floors if you need to
• You're never too old to exercise - if you don't fancy something too strenuous, consider something gentle like a Tai Chi class which will help your breathing, posture and balance
• Think exercise is boring? Join a jazz or salsa dance class - it's a great way to make new friends as well
• If you're concerned about aching joints or a troublesome back, consider swimming - it's inexpensive and the water will support you
