Absolutely, haha. Thanks for clarifying. I guess I didn't phrase my thoughts on your fitness program as well as I'd hoped. What I meant was it doesn't appear that the program is building strength, specifically. It may very well keep you in good shape, burning fat and helping cardiovascular fitness for example. But I believe the ability to do a chin-up is a good indicator of overall upper body strength, since it employs several different muscle groups. I didn't mean the fitness program is bad in general, just that it must not be creating a lot of upper body strength. If upper body strength / endurance is something you would like to improve upon, then weight training would probably give the best overall results. Just something to consider.
