While some of you have your healthy lifestyle down to a tee - balanced nutrition, adequate sleep and a finely tuned workout regime incorporating strength, cardio and flexibility training - others struggle to know where to start when it comes to fitness. And with Google searches for "Is 30 minutes of exercise a day enough?" spiking, it seems that many of you aren't sure about the length of time or number of workouts to aim for weekly.
And to make matters even more confusing, knowing how often you should workout isn't always as simple as it should be. You see, your progress will depend on a combination of factors which might seem unconnected to exercise but still have an impact. Sleep, for example, has been shown in various studies (like this one, published in the European Journal of Applied Physiology) to affect physical performance, while research also shows a bi-directional relationship between exercise and stress.
