We only grow if we push ourselves to the limit, test our edge and expand our capacity as often as possible. Turns out that putting ourselves in that position is usually really uncomfortable..sorry I'm not sorry about it. Excuses are just a way for us to avoid doing the hard thing, a way for us to let ourselves off the hook. So what if you set a goal to get your pull ups down, there are like 50 pull ups in this workout so you've gotta use all the bands you can find because otherwise it'll be too hard. Sure you want to get stronger, but lifting all those heavy weights means you won't always be able to finish the workout first in class. Gotta have a beach body ready for summer, but hey, it's been a long day so this donut is okay, right?
Your excuses are letting you down, and when your behavior changes due to an excuse, you're letting the excuses win and you're letting yourself down. There's never a good reason to let yourself down; being old, hungry, tired, busy, overworked, stressed, sore, worried, embarrassed, too hungry, too full, or just being lazy..none of these are acceptable reasons to let yourself down.
As Jack Lalanne says: "Remember this: your body is your slave; it works for you." So set your goals, make yourself a priority, and begin a relentless pursuit of excellence and growth.
