This once-a-week workout may help cut belly fat, study shows

A study suggests that a surprisingly small dose of exercise may deliver significant health benefits for adults carrying excess fat around the waist. In a four-month trial, 315 adults with central obesity participated. Researchers found that completing 75 minutes of brisk interval walking in a single weekly session led to reduced body fat. It also resulted in trimmed waistlines and improved cardiovascular fitness. These outcomes were about as effective as splitting the same exercise across three days. This indicates that even one intense workout per week can be effective for health improvement.
