Again, keeping true to form, this is likely gonna sound nooby- so Im sorry and appreciate whatever feedback I can get.
Say you're halfway through a session and you get a callout you cant avoid; be it work, family emergency, whatever- you have to up and leave the gym at that moment.
Is it a case of just get back in the gym as soon as poss, accept you might have to waste a little more time re-warming up and getting back there, but more or less you're good to go without sacrificing much of the whole workout's efficacy? Or is that going to have a serios effect on the quality of your day's exercise; and if so, why (beyond the fact you're probably going to be a little more tired by the time you re-enter the gym).
Thanks again guys; this is by far the best bodybuilding forum I have seen.
