In this special edition of You and Yours, Shari Vahl investigates ways to get more physically active this New Year.
With the help of the 大象传媒's science journalist, Dr Michael Mosley, she looks at how to get started and the secret to sticking to a new exercise routine.
With self-deprecating humour, she finds inspiration in surprising places and learns to cope with failure along the way.
Shari sets out to discover what's stopping her - and around 20 million other people in the UK - from doing regular exercise.
According to the British Heart Foundation, 39% of adults - a third of the population - are just like her, doing no exercise at all.
Both the figures and the public health messages are stark - physical inactivity increases the risk of heart disease, dementia and some cancers.
Experts tell us that if current trends continue, half of the population will be classified as obese by 2050.
In her quest to get fit for the New Year, Shari tries strength training, high-intensity interval training or HIIT, hot yoga and running for beginners.
Along the way, she speaks to experts including Dr Charlie Foster, the Chair of the UK's Chief Medical Officers' Expert Committee for Physical Activity, and Professor Angela Clow, a psycho-physiologist at Westminster University.
She also visits Rotherham in South Yorkshire where 76 per cent of the population is either overweight or obese. She meets Dr Matthew Capehorn who runs the Rotherham Institute for Obesity to discuss the role of exercise in getting people back to a healthy weight.
