Im normally a pretty private person so i dont discuss alot about me on the board. Heres the thing, about 3 years ago i had a bad accident which means my legs, back and shoulders are pretty screwed up. I got severely depressed, ballooned and generally gave up on everything.
About a month ago i figured i'd give lifting another crack to see how my body would cope so i started doing pushups, dips etc at home and then last week i joined a gym. I love it, felt really good but at the same time it is incredibly humbling seeing juiced up monsters shoulder pressing 4 plates like nothing on machines.
My primary problem seems to be endurance, the weights im using are light to me but after 3 -4 reps i just seem to run out of steam - is this normal (lactic acid etc)? Im hoping it'll go away in time once im back in the swing of things but its really concerning me. My legs are still pretty strong but upperbody is a wreck. Worked shoulders for the first time today and was in agony using 15lbs for side laterals, would it be better if i just left shoulders altogether? I felt humiliated sitting there pressing 35lbs when most people were 100+.
Thanks in advance, any advice would be greatly welcome.
It may be a matter of devoting more work to your Type I slow twitch muscle fibers, which are the endurance fibers. These fibers are used more for reps while Type II fast twitch are used for heavy singles/doubles/triples.
Some literature uses the analogy of marathon runners to sprinters, but the underlying premise is that slow twitch=longer duration activity, while fast twitch=short, explosive activity.
Most people have a fairly even ratio of Type I:Type II, but some have a dominant fiber type; meaning they have more of one type than the other. Regardless, many trainers fall into the trap of training only one fiber type and neglect the other. If your endurance fibers are underdeveloped, it may behoove you to focus on them more for a while.
