Jogging may be your ideal form of aerobic exercise. It tunes up your cardiovascular system, tones your legs, lets you blow off stress and can burn upward of 1,000 calories per hour if you dig deep enough. Some people are committed morning exercisers, while others prefer to get their workouts in once the sun goes down; benefits and drawbacks exist for each.
Advantages of Morning Jogging
If jogging is the first thing you do when you roll out of bed, then, if nothing else, you've gotten in your workout for the day. Jogging in the morning helps you start your day on an upbeat note, burning several hundred calories right off the bat. If unforeseeable events land in your lap later in the day, as an early-morning runner, you've still managed to avoid a goose egg in your training log.
Disadvantages of Morning Jogging
Not everyone is cut out to be a morning jogger. If you're in the ranks of those who have a hard time getting going first thing, all is not lost -- in fact, depending on where you live, chances are good that it's dark outside when you wake up, at least in the winter months. Motorists may not be able to see you very well unless you wear reflective gear, and some people report feeling creaky or unenthusiastic about exercising before doing anything else.
Advantages of Night Jogging
If you wait until nighttime to jog, you can ensure getting some fuel into your body and starting your workout much less stiff and creaky than you do when jogging first thing in the morning. If you like to jog with others, it may be easier to secure a training partner later in the day, and you can start your jog knowing you've taken care of whatever family and work obligations you have that day.
Disadvantages of Night Jogging
Jogging at night has the obvious disadvantage of leaving you in the dark, assuming you don't run on a treadmill. Depending on where you live and jog, it may also be unsafe for other reasons -- if you don't live in the best of neighborhoods, you could become a target of muggers and others bent on ill behavior. If you live in northern climates, it may be considerably colder at night. Finally, you may be cutting into family time if you delay your jog until the evening.
