“Zone 2 cardio refers to exercise performed at a low-to-moderate intensity where the body relies primarily on aerobic metabolism and uses fat as a major fuel source to produce energy,” said George Yusuff, MS, exercise physiologist at HSS.

“Zone 2 training provides numerous heart health benefits because it strengthens the cardiovascular system while placing relatively low stress on the body. One of the most important adaptations is an increase in stroke volume, meaning the heart becomes stronger and more efficient, allowing it to pump more blood with each heartbeat,” Yusuff said. “As a result, the heart does not need to work as hard during exercise or daily activities.”

“Gluteal amnesia, often referred to as ‘dead butt syndrome,' occurs when the gluteal muscles become inhibited and fail to activate effectively," said Yusuff.

To avoid dead butt syndrome, you should try not to pass long periods of time in a seated position. Yusuff recommended trying to stand up and move around regularly. “While this can be challenging with desk-based work, aiming to stand up and move at least once every hour, ideally every 30 minutes, can make a meaningful difference,” he said. “In addition, incorporating glute activation and strengthening exercises is critical for restoring proper function and improving strength in the glutes.”

Your risk of injury increases with age, but implementing certain exercises into your routine—particularly after age 40—could help reduce this risk.

Although the risk of injury increases as you age, the benefits of exercise far outweigh the risk. Partaking in exercise—both aerobic and resistance, when done safely and appropriately—helps to slow the decline of these age-related changes and can also help to improve quality of life, longevity, and reduce all-cause mortality risk.

"When you’re walking, there's a lot less demand and impact on the body, so it's a good way to reduce injury risk," said Yusuff. 

“If you start to run then you get injured, that can sometimes put people off forever,” Yusuff continued. So if you've never run before or you're getting back into it, jeffing may be a helpful strategy.

Another potential benefit is that it may shorten recovery time. "During the walking stages, you slow the body down, kind of lower (core) temperature and recirculate some of the lactate that accumulated while running," explained Yusuff.
