The first goal, gaining muscle or strength is more often than not going to be a lack of proper programming and progression. If you're not documenting your training efforts, chances are you aren't progressing, and you most certainly are not programming. One principle that I will bet on every day of the week is: Your body will adapt to the demands imposed upon it. If you understand what "adapt" and "impose" mean, you'll be fine. Hopefully you can deduce from this that if you don't change some component of your training (exercise selection/variations, rep ranges/loading, core/assistance work) you're going to go stale. The human body is always in flux, and therefore is unbelievably effective at adapting. Takeaway: if you allow your body too long to adapt to the same training routine, it's going to become increasingly efficient at accommodating it and eventually stop responding. To avoid this problem, pay attention to your weights and rep ranges, not only on core lifts, but assistance work as well. If you're not willing to change the exercise, (you are still seeing some progress) up the volume or the intensity. If you're not seeing progress, change the exercise altogether. This applies to both core and assistance work. More specifically, if you're not seeing progress on core lifts over a reasonable period, change your assistance work, and rotate core lift variations once every couple weeks.

With respect to the last goal, your hindrances will be contingent entirely on what you decide constitutes better fitness. Is that going to be an increased aerobic capacity? maintaining a "healthy" weight? making it through your day with less difficulty? In any scenario, increasing 'fitness' in one way or another is going to make your body more effective at maintaining internal balances and thwarting physiological disruptions. Of particular interest to you may be that a trained subject is going to possess a body that is better equipped to burn calories at a higher rate during bouts of exercise. Say a typical untrained person may burn about 5cal/minute, and a trained individual may effectively burn 10cal/minute. This lends at least a bit more hope to those of you who were upset after reading the last paragraph.
