Stamina is really just a combination of energy, physical endurance, and mental tolerance. Having a large amount of stamina will allow you to work out longer, more often. If you can exercise more, you’ll see better gains in your fitness – especially as you start to see the diminishing returns losing weight and gaining muscle.
It really plays a large part in most aerobic exercise. The single biggest muscle in your body that affects stamina is your heart. Have a healthy heart, and you’ll see tremendous gains and feel amazing too. You’ll also be protecting yourself from illnesses like heart disease and high blood pressure.
Energy
Consuming energy producing nutrients in the few hours before exercise will boost your energy. Consume foods high in electrolytes and carbohydrates. A turkey sandwich on whole wheat bread with veggies on the side. Have a nice tall glass of milk with that too. I prefer skim milk myself.
The best place for electrolytes is not a drink by the way. Get some real vegetables or something that has a lot of flour in it. Don’t get conned into the Gatoraid thing – although that is also a decent place to get them, it’s not the ONLY place.
Physical Endurance
Your physical endurance is affected things like the health of your heart and muscles. It also includes things like injuries or physical condition. What do I mean by physical condition? Fore example: are you dehydrated? If you’re low on water, you’ll perform miserably and probably quit early.
The only way to improve your physical endurance is to challenge yourself daily and increase the health of your heart and muscles. Observe good habits that keep your body feeling good too, like a healthy diet.
Don’t overdo the physical challenge. If something is just beyond your reach, dial your routine back a bit. If you’re running, run slow (don’t run less, just run slower). If you’re walking at an incline, shallow it out a bit. You will have good days and bad days. Listen to your body and perform at your maximum for that day.
Mental Tolerance
When exercising, there are two mental roadblocks that rear their head. They are: boredom and the pain of real gains. The only way to truly overcome them is to attack them head on and use willpower to get through.
You can help stave off boredom a little bit by watching TV or listening to music while you work out, but ultimately that just distracts you and will affect your performance. You know when you’re driving and don’t really remember the last few minutes even though you know you were awake? Go for that kind of autonomy during an aerobic workout. You might not want to check out during strength training though.
Bringing it Together
Actively work towards increasing the performance of those three facets of your stamina and you’ll see gains. When you increase your stamina overall, you’ll see an acceleration in your overall fitness gains. Be careful you don’t overdo it and be safe while you’re training. Are there other ways you work to increase your stamina? Let me know in the comments.
