As we discussed with cardio, we often talk about strength training in terms of the long-term benefits. Yet your brain really cares about the instant rewards of doing something. But what if the instant ‘reward’ you get from lifting weights is muscle soreness and fatigue? Sure, you could tell yourself ‘no pain, no gain’ and convince yourself that it is a ‘good sore’ and all that discomfort means you got a ‘good workout’. Your brain, though, is most concerned with you feeling good now and it’s designed to avoid things that are painful or uncomfortable. When your willpower to endure the discomfort runs out, your brain will start to plant excuses in your head about why you need to skip strength training today (and the next day, and the next).
Eighty percent of people are not doing strength training. Like you, they probably know the benefits—stronger bones, better aging, stronger metabolism—but the brain has some concerns—injury, weight gain, getting ‘too muscular’, or looking like a weakling at the gym. This keeps many people living in the ‘should’ when it comes to strength training.
Are you ready to get out of the ‘should’ when it comes to strength training? Ready to reassure your brain that it is all good, because you are going to work with how your body is designed to be strong? Let’s cut through the marketing- and myth-based ‘facts’ and clear the path to your strongest possible muscles, bones, and metabolism now and every decade going forward.
What is strength training? Strength training is also known as weight training, weight lifting, and resistance training. Basically, it’s when you challenge your body to be able to move your body or objects more easily against gravity. If you are thinking the things you do in your daily life like housework, child care, and yard work mean you don’t need strength training, click here to see why these physical activities are different than exercise.
Making your brain want to strength train. From the very first time you do a strength exercise, you set into motion a cascade of events that produce unique and powerful events in your whole body. Yet, most of the effects of doing or not doing strength training are not noticeable right away, so it’s easy to forget why it is so important. In the next few blogs, I’ll show you the Real-time Results of each strength training session, and why pain and discomfort are not necessary. This way, your brain will be more confident that doing strength training will help you feel and function better now, without having to first endure pain, discomfort, or embarrassment.
Why strength is not from your muscles. Although we most equate strength with big muscles, that is not where strength comes from. Before you even move, something very important happens. Your brain is activated and ‘plans’ what muscles will be needed to create the intended movement. It estimates how many muscle fibers are needed to create the force you need to move against gravity. Then your brain sends a signal through your spinal cord to the muscles you need to do that movement. Without this nervous system signal, muscles can’t move. This pre-planning of movement makes it much smoother and more efficient.
The pathway to strength: Just like the first time you take a trip somewhere, the first time you perform a movement, your brain has to work harder to find the most efficient pathway. Over time, it becomes easier as your brain remembers the pathway. Think about how your body learned to walk, ride a bike, tie your shoes, swim, or play sports. All of these are examples of this process we call muscle memory. This building of muscle memory is what makes movements more automatic, so you can gain coordination, balance, agility, and strength.
Confusion about muscle memory: There is some talk that muscle memory is bad, because you burn fewer calories as your body gets used to an exercise and that you need muscle confusion to keep your body burning more calories. Honestly, the calorie-burning difference is minimal and probably won’t add up to any change on the scale. Muscle memory is what allows you to function. If you are exercising to lose weight so you can feel and function better, muscle memory is your friend.
The strength of your brain. Since the brain and nerves are what tell your muscles how to move, strength originates in your brain and nervous system, not in your muscles. That means you need your brain for building strength. You can see why present moment awareness is so important to get the most from strength training. It ensures you are creating the nerve pathways you want, the ones that allow you to access your strength by positioning your body in the right way, and creating nerve pathways so that strong movement becomes more automatic (more on that later). If your brain is distracted by a TV show, or other people around you, it won’t have as much ability to put into building your strength. If finding the time for strength training is a concern, choose high-quality strength training by focusing your attention on your body rather than trying to save time by multitasking and doing it while watching TV
Bottom line: Your full mindful attention is your best strength training tool!
In the next blog, we’ll look at what happens in your muscles when you strength train that continues the cascade of events that leads to you feeling and functioning better.
