Congratulations on moving forward to the next phase. Definitely measure each month. I am so glad I did that. I plan on continuing it each month. Scale weight is okay for long-term trend, but measuring will give you true feedback. I also used those calipers and plugged the number in the Beachbody fat calculator they have on their site. Who knows if that is accurate.
Maybe you can sell your weights on Craigslist and buy some used Selectechs on Craigslist...they are so worth it.
Thanks for your comments on my page. Very pleased with my results. next week begins P90x Turbo Fire hybrid
