Finding a good workout routine can be a daunting task for an uninitiated newcomer. With so much information widely available in print and online, the fitness newcomer is often overwhelmed about trying to sort through all the different advice and settling into a routine. It's important to remember to just breathe, relax, and keep it simple. Exercise routines range from walking the dog to complex bodybuilding stacks, and just because there are always more complicated routines out there, that doesn't mean they're right for you. Work your way in slowly to avoid discouragement, and try one of these five easy routines:Interval Training. Interval training has consistently shown to be one of the quickest and most effective ways to improve aerobic and cardiovascular health. Simply put, it consists of walking or jogging slowly for a set time, then alternating to jogging, running, or even sprinting. There are many charts and structured programs that can break down specific interval sets for improving heart health over time, but you can start anywhere with just a watch. Start off by alternating between a slow jog and a walk for one minute each.Sports. Exercise happens outside the gym too. Chances are there's a sport you've thought about giving a try, or perhaps you want to rekindle a sport from younger days. Many intramural and recreational leagues are available, most of which are beginner friendly and non competitive. This is not only a great way to exercise, but can quickly expand your social circle and help you meet new friends.Get Aquatic. Many people who are severely overweight or have joint problems find getting into the pool to be much more comfortable than aerobic or strength training. Swimming burns more calories than running, and it's a great way to give your whole body a workout.Circuit Training. Circuit training differs from traditional strength training in that it moves quickly between exercises and tends to work more of the whole body than concentrated lifting. This can be an excellent way to get your joints and tendons used to the strain and avoid future injury.Plyometrics. Plyo exercises cover a much wider range of alterations and variety than pumping iron. Box jumps, depth jumps, exercise and medicine balls, and even jump rope can have exponential advantages to your overall health, and stave off boredom.Lastly, don't forget to have fun! The more you switch up your exercise routines, the more engaged you can keep yourself.
