Work Your Heart
The most beneficial exercise is the kind that elevates your heart for a significant period. Activities like baseball may be physical and prolonged, but they don't keep the body working throughout the game. You should work out 3 to 5 times a week in a way that keeps your heart rate elevated for at least 20 to 30 consecutive minutes. Doing so will improve your body's blood flow, heart health and energy levels.
Cross Train
In the pursuit of fitness in one venue, you can actually do your body a disservice. Individuals who work out solely on bikes are at a higher risk of bone thinning. This is because the skeleton is not enduring its intended work and stress. Cycling is an excellent activity, but complement it by periodic workouts off the bike, such as running, swimming or lifting weights. Team sports and hiking are also activities ideal for cross training--anything that offers a workout in a different way than your body is accustomed will help keep it healthy in all aspects.
Eat Healthy
If you work out daily but think it earns you no restrictions at the dinner table, think again. Your diet and activity levels determine your fitness. Make sure you eat a balanced diet high in natural foods like fruits, vegetables and lean meats and low on sugars. High blood sugar levels can lead to energy crashes and make it harder for your body to regulate your energy.
Know Your Limits
As men age, they sometimes feel the impulse or desire to test their limits and see if they can physically accomplish what they once were able to do. If you go beyond your realistic limits, this can cause injuries ranging from minor muscles strains to full muscle tears and even cardiac problems. Exercise within a safe zone that tests you but is not beyond what you know you can do. Injuries of any kind are counter-productive to fitness. They damage your body and take it out of commission, rendering it useless until healed.
