No problem. I'm no expert, but have some experience. And thanks for the post to my gym log, figured it was just going to be me recording things
Hmmm, Never done what you are talking about, so can't comment on effectiveness, but it sounds more like a stength building/endurance building exercise, versus trying to really tear down the muscle and build it back up like weight training does.
I can't recommend enough the simple crunch (and variations when you get more into it) for ab work. Everything I have ever read points it as the best/easiest exercise to do for your abs. Do you know how to do a crunch? Kinda like a 1/3 situp? If not, ask, I'll explain.
I really like how BFL does them, and all their exercises, since I really like that pyramid approach.
You asked about BFL, focused on the intensity. This is what I like about it, it is just your take on how intense the exercise is, so it is completely up to you to how much weight you lift, where you make your weight changes etc....
For example, since a description is better than trying to explain I think, take my shoulder routine.
I have dumbells in 5lb increments. So, for shoulders I start with a 5lb dumbell in each hand, and do a shoulder press - sit and hold the weights by your ears, press up above your head until extended and back down. 12 reps, then rest for a minute, and I find this to be effort, but not really that much, so I count it as a 5. I then go up to 10lbs, and do 10, a bit more effort to complete, I rate it a 6. However, 15lbs is too much for me say at the 8 rep level, so I just keep the 10lb weights and do it again. This is somewhat more effort, since I've already done 2 sets, and then so on. The biggest thing when doing this is to be honest with yourself. I find I challenge myself to see if I really can't do 1 more rep at the higher intensity levels, or if I just want to give up because it is burning.
I don't think you have to be in shape to start with, because you can just pick things that you feel gives you the intensity you are looking for.
But, it really took me a 2nd read through the book to figure this all out, since the first time through I was rather confused about it all
But, I think anything that works the body can't be bad for you
I will say though, that the BFL cardio is the first time I really felt like a cardio session is doing something for me, beyond making me sweat. And as it is only 20 minutes, it is so nice to fit in.
Anyway, anything else I can answer, or help on, let me know.
Oh, I have some experience in the past with exercise, but nothing ever too serious. In highschool I fooled around with weight bench and barbell, nothing ever came from it. In Univerisity in the 2nd year I had a roomate who was into Karate and body building, and I spent a few months working with him in the gym, where things were pretty intense, and I did build a bunch of strength, and probably some muscle
When first starting work full time, my now wife and I went to the gym 3 times a week for a year, and that was the best shape I had been in until now from a weight perspective, and I'm working on the muscle/endurance with this current run.
I've read a lot on weight training, more than I ever actuall put into effect, and I am no expert with just really some practical experience with some theory.
hehehe, Ok, I've rambled enough, have a great day.
