Nobody these days has time to waste; we are all busy people on the go. So why spend hours in the gym if you don't have to?

The truth? 30 minutes is all you really need, and an hour is too long for most people whose goal is usually fat loss. Including proper warm-up and cool down methods, your workout should only last about 45 minutes with 5-10 minutes of warm-up and 5-10 minutes of cool down, including stretching.
