It’s not suppose to be easy. In fact I’m glad that it’s not. Over the course of human evolution we’ve reduced the amount of physical labor that we have to do and increased the time we spend sedentary. Back when we were hunters and gathers we were far more functional if for no other reason than we had to be. You had to chase your food and at times be chased by it. So your life revolved around the fight or flight instinct.
In todays world you can get any time of food you desire by simple walking in the supermarket. You don’t even have to walk, you can get one of those scooters (man I hate those things). This is one of the biggest reasons why starting an active lifestyle is so difficult. Our world isn’t designed for it and so it takes a great deal of effort to condition our mind to it. Here’s the kicker it really only take 2 weeks of consistent work to develop neuromuscular efficiency. Now I don’t want to get too technical, so neuromuscular efficiency is basically conditioning. It’s when your nervous system can effectively communicate with your muscular system. Your nervous system dictates all movement and because the body is designed for self preservation it causes funky things to happen in an effort to protect you from harm. The most common response to what the nervous system perceives a over exertion is vomiting which forces you to stop all activity. Even though it only takes 2 weeks of consistently working out to develop neuromuscular efficiency if you are inconsistent it can take forever.
