I work out in a well-equipped gym 4 times per week, and this question is about weightlifting in particular.
When I work out, I'm always painfully aware of what my weaknesses are, and I want to be able to catch them up in a way that makes sense.
The concept of "weakness" in this context should be understood as
an exercise that is disproportionately lagging behind or
an aesthetic shortcoming, e.g. visually underdeveloped deltoids
I'm going to try and stimulate my weakness by performing 1000 repetitions of said exercise or an exercise for said muscle group, over the next 10 workouts.
After one such cycle, I will find a different weakness, because it would likely be disastrous if I were to continue with the same one for consecutive cycles.
This regimen will not replace a normal workout plan, but rather be done as an auxilliary type movement, with a very modest choice in weight. I.e. I will continue training my entire body.
Any exercise chosen will be a compound lift, and not an isolation exercise.
For example, if I deem my deltoids underdeveloped, I will attempt to fix this, not by lateral raises, but with military press, shoulder press, or maybe jerks.
For reasons of self-preservation, I'd likely not attempt this with the heaviest of heavy lifts. Specifically, I'm thinking of excluding deadlifts from this regimen.
Are there any concerns about this idea that can be attributed to documented cases of this going wrong?
Naturally, success stories are equally, if not more desirable.
In order to avoid this being flagged as opinion-based, I'm looking for concerns based on research. Anecdotal evidence, if documented, is also welcome of course.
Also, as a solid answer might require more information, please ask and give me the opportunity to elaborate, rather than flagging on sight.
