A slightly more off-the-wall resolution this year could be bursting into song.
People often like to get fit in the new year, but a 90-minute session with Rock Choir burns about 200 calories, because they dance as well as sing.
Rock Choir leader Sam Smith, who runs weekly sessions in Esher, Weybridge, Epsom, Dorking and Chobham, said: "It's amazing to see how much the members benefit from taking part in rock choir on a weekly basis.
"I've seen confidences grow and friendships develop and it's awesome to see, especially when they have taken part in a performance."
Rock Choir is the UK's largest contemporary choir, with more than 17,000 members in more than 300 communities.
