We all want to be strong, look good, and feel good but strength training goes beyond that. While we don't have to look like the lady above, strength training is a good way to improve overall health, mentally and physically. You're probably asking "what is the point if not to look "incredible"?" Let me shed some light. To engage in strength training does not mean you have to be incredibly ripped, strong, one big mass of muscle, or even "in shape". The key is to start with where you are and push yourself to get to where you want to be. ( it may sound cliche but it's true) Don't try to exceed your limits to the point of hurting yourself but also go a bit beyond what you think you are capable of. In my experience strength training goes further than the gym, it extends into our everyday lives. There are times in training where you will think you are not capable and feel the effects of the confidence and accomplishment when you push through, overcome, and do what you thought you couldn't. Going forward you will find yourself being full of more confidence and believing that you can do more and are capable of doing hard or uncomfortable tasks. Strength training is good for you mentally because of those reasons, it takes you out of your comfort zone and pushes you to rely on your resolve and resilience. Many people see positive changes in their self esteem as a result. Now lets get to the physical benefits. Obviously strength training can make you look great if you put in the work and that is a great benefit but not the only one. Some other benefits are gaining strength, losing weight, forming good posture, strengthening your bones carrying out everyday tasks easier, and long term benefits that help your body and mind in old age.
