While many make new year's resolutions to get in shape, September is actually the most popular month for people to join the gym, according to LA Fitness.

A spokesperson for the fitness chain stated that although the beginning of the year is perceived to be the most common time to join the gymnasium "as part of the traditional new year resolution frenzy", September is the most popular month for new joiners.

The spokesperson added that the industry as a whole expects more than 100,000 new people to sign up in January, adding that many consumers start "very enthusiastically" and visit up to five times per week, but may then give up after a relatively short period of time.

It was suggested that members may benefit from better longer-term results by visiting twice per week and taking time to recover between workouts.

According to Weight Watchers, increasing physical activity can help break through a weight loss plateau.
