Cleaning Up Is More Effective to Prevent Obesity Than Going to Gym
A study by the National Institute of Health and Nutrition in 2013 reported that sustained exercise is not necessarily required to prevent obesity. Rather than spending time running or in the gym for a sustained period, it is more effective to exercise intensely in short bursts throughout the day. The study found that the latter resulted in more effective fat burning.
A former researcher of the institute claimed that rather than doing one exercise for one hour, it is more effective to burn fat if you make small movements such as cleaning up.
However, this applies to the case of prevention of obesity. In the case of someone who is obese and need to lose large amounts of weight, stronger exercise would be more effective.
