I think some people have the wrong expectations about what it takes to get stronger and fitter. Yes, it is “fun” in its own way; usually after you’re done with the workout or enjoying the results of being consistent and committed.
But it is hard. It is supposed to be hard, and that isn’t always pleasant while you’re doing it. Actually, if it is pleasant during the actual lifting and working out, you aren’t training hard enough. It kind of sucks right in the middle. Your body may be hurting, you’re breathing hard and sweating, your heart is pounding, and you may even feel slightly nauseous.
But, you have to push your body past the comfort zone to shake it up. Make your body say; “What in the hell is going on? Since when do we need to keep lifting heavier and heavier weight, or running faster and faster? I better make some friggin’ changes to this body to handle this crap that this crazy fool keeps throwing at me.” And that is when you grow.
