High-Intensity Interval Training (HIIT) like cycling, push-ups, burpees, squats, and lunges may not just delay cognitive decline in the elderly but also boost brain function that can last for years, according to a study on Wednesday. 

The study by the University of Queensland in Australia found that six months of high-intensity interval training can boost important brain functions such as hippocampal-based learning and memory in older adults for up to five years.
