Don’t “work out” unless you are prepared to attempt a new personal record, in terms of overall weight, or repetitions.
This means, for any given movement, do not do it more than once a week. For example, if I attempt a new one rep max for my squat, and whether I succeed or fail, I will not do it at least for another week.
Even with bodyweight exercises, let us say it comes to chin ups. I will not do any chin ups, unless I do it as an attempt to attempt to break my previous personal record for the number of total chin-ups I can do.
Even with kettlebell exercises, don’t just do it every day or every day as a form of discipline training. Rather, better to attempt a new personal record in any of your kettlebell swings once a week, than to do it every day with regularity.
