Fast twitch/ Slow twitch

babyg25 Posts: 38 Joined: 2002/08/13	2006/02/03, 06:13 PM i was at the gym during teh week doing body pump in a group fitness class and, going with my goal to lift heavier this year, i put my squat weights up. my legs gave up half way through the track and it was shear will power that got me through lol. they also stayed like jelly throughout the rest of the class and were shaking, now considering the squat track is the first track you can imagine what fun the lunges at the end were. so i asked the trainer why my legs gave up so soon after starting the track and he started talking about fast twitch/slow twitch and i haven't got a clue what he was talking about. my upper body has always been way stronger than my lower body (which doesn't make much sense to me as my lower body had to carry nearly 300lbs of weight for over a year) Can someone please explain this fast twitch/ slow twitch to me in extremely beginner format lol and should i be working on my lower body more in the gym to combat this?

I could make a real long post explaining fast twitch and slow twitch, and which muscles contain more or less of each, but not worth it. Just assume for ease sake that most all muscles are evenly divided, and forget about it. :big_smile: Not trying to make light of it, just it can be overwhelming and it is very difficult at best to try to isolate th4e fibers. Then you can throw in type 2A, and it gets even more overwhelming. Different rep schemes "target" different fibers, but it is difficult to do. -------------- Strength and Honor!

Like BB1Fit said, its not really worth thinking about if your just starting out. It's like worrying about supplementing when your still not eating clean. It's just icing on the cake. -------------- Iron and chalk. Pain is only temporary, it is in your mind. If you can still walk, then you can still run.

But I gotta admit, I'm kinda worried lately every time I post. What if I screw up??? The other day I was reading thru some of gatormades threads and came across one about calling people out on bad advice. To be honest with ya, it kinda freaked me!!! And I gotta say...if he ever calls me out...I'm going invisible!!! JK gatormade, that was a very good thread on professional advice. Too bad their isn't a filter. Now...lets get back to this whole fast twitch/slow twitch thing...I usually find it best to just go with a good medium twitch but that's just me. Whatever works best for you! OH STOP IT, I'M JUST KIDDING...ok I'm gonna go wrestle with my kids now...enjoy your ay everyone. -------------- Seize the day!

	2006/04/01, 12:42 PM All the posts that involve words like anabolic, catabolic, hypertrophy, slow twitch fast twitch and such have always sent me into a paroxim of lip diddling. Let Menace, BB1 and Wrestler have their debstes which we mortals were never meant to understand. These guys are kind of the Einstiens of fitness. Just keep your eyes on the prize and keep doing your routine. -------------- Sometimes life is like herding cats. Charlie
