Once the warrior mindset has taken hold and you are hooked and making progress, this won’t be a problem. However, the first few weeks can be the toughest, especially once the first few aches and pains start setting in post-workout. Develop a mental rule. If you plan to do a workout, just do it!! Or if you don’t feel like going to the gym, commit to doing one exercise, just one exercise. Evaluate how you feel after that, more often than not you will just get on with it. Even if you do that and go home, doesn’t matter, you have done that one exercise, it’s progress no matter how slow.
