1. Men who work out with a female partner are shown to lift heavier weights and get better results. This is most likely due to our social tendencies as a species more than anything. Humans are social creatures, having other people around who have similar interests serves as good motivation. Also, no one wants to look weaker than other people around them.
2. Mind over Matter: Mental exhaustion is a real thing. Long before people get physically exhausted in a workout, where their body cannot handle anymore and needs to stop, they get mentally exhausted. Mental exhaustion is something that can be adapted to and overcome (for longer and longer amounts of time) with integrated training. Once you realize that it is possible to keep going past the point where your mind tells you to throw in the towel it becomes easier to learn the signs of actual physical exhaustion and listen to those instead. Mindset is a huge part of everything in life, exercise included. Doing something mentally draining before a workout actually hinders your workout. Same with feeling extreme disdain for workout our, or feeling intimidated by it.
Something that helps me a lot when I'm tired or things start getting boring, is remembering what I'm doing is a choice, and the benefits of it are worth it. Going from a mind set of "Ugh I have to do this" to "I'm CHOOSING to do this." is a small, easy shift of thinking that can have big impacts.
3. The word gym comes from the Greek word "gymnazein"... which literally means "to exercise naked". Maybe that explains the people with no shame who lurk in every chain gyms steam rooms from time to time.
4. Exercise is more effective at increasing your energy levels than caffeine. Exercising does amazing things for energy because it does it at a cellular level. Increased demand on your body to produce energy (like for cardio exercise) makes the mitochondria in cells produce more energy, which stays readily available. The more consistently you work out, the more mitochondria get produced and the cycle continues.
5. Music is Power: In a way, it literally is. Studies have shown that people who work out while listening to music improved their performance by up to 15% compared to working out without music. Listening to music can help people in multiple ways, but two of the big ones are: avoiding mental exhaustion and (depending what type of tunes you sweat it out to) stimulating adrenaline production.
Music breaks up the monotony of a workout, especially long endurance training cardio sessions. Keeping yourself mentally stimulated and getting enjoyment from the music makes the entire workout more enjoyable. Multiple studies (and common sense) show that the more a person LIKES their work out the more likely it is they will stick with it long term. As far as the adrenaline goes, some music - especially with heavy basslines or fast BPMs - can stimulate adrenaline.
Exercise and fitness are so multifaceted, and have some kind of effect on so many different things, sometimes in surprising ways.One thing for sure though, it's always beneficial. Get it in!
