Hey hope someone knows the answer to this question.
Why do I get tired quickly at the gym while others can keep going for ages?
I'm an ectomorph through and through; tall, skinny, good at endurance sports like running. So I would say I have a lot of slow twitch muscle.
I go to the gym with a mate whos a proper mesomorph; he's always been big and packs on muscle like crazy. He probably has a lot of fast twitch muscle.
My instincts would tell me that due to my slow twitch muscle I should be weaker than my friend but be able to lift weights all day, however I find that the opposite is true.
On our first set we can both do the same weight for the same number of reps to failure. However I get tired quickly, my reps drop quickly and I need long rest periods between lifting.
My friend can keep hitting the same muscle all day and still do heavy weights.
To give you an idea of what I mean my friend will do 6 sets of heavy bench, then 6 of incline bench and 6 of decline, then he'll finish off his tri's with some pulldowns. Myself, I do 4 sets of bench and I'm done, I can't even imagine working the same muscle twice in one gym session, they just stop working after one exercise.
Why is it that my endurance suited muscles have zero endurance when lifting heavy weights? I was thinking maybe it's due to the difference in working aerobically or anaerobically?
I'm so confused >_<
