Reality check time. I measured and what I thought was a mid 30s PR jump is actually a legit PR of ....... 27.5". So when i've been going on about 40" i am actually below 30". That kinda sucks. I have work to do. I should probably just do that cut to 70kg but i'm not sure it's a good idea to do it in one hit. Maybe i'll get sub 75kg first and maintain that and then later down the track go 75->69kg or whatever. Do i even care bout my vertical that much? I dont think so lol. Maybe i should do it just to see what it is like being in single digit bodyfat range .. then do small bulks around there not getting too fat again.
That doesnt suck. If your dunking w a 27" jump your reach must be pretty impressive, like at least 8'4" or so... Only jumping 27" inches means that you can realistically jump 10-12"" higher w training, imagine the dunks you will be able to do? If your jump was 36" now it would be a lot less likely that you add a foot of jump height... finding weaknesses is always a positive when your goal is improvement!
Your like 6'4"? Your goal is to cut to 69kg?? Thats 150lbs! 6'4" 150 is extremely skinny - even by high jumper standards thats way too light...
Im a lot closer to agreememt with a lot of the stuff you do as far as bw manipulation when compared to the other posters... i dont have a problem with frequent weigh ins and your monitoring of bodyweight... but this is something your taking too far...
You should take your 27 inch jump into account here... you keep losing bw to jump - you think it works. But considering that your only jumping 27 inches should be evidence that your weak. Cutting bodyweight will work if your weak - weak people are not powerful at 200 or 170... but if you want to make major changes your gonna have to get strong and powerful rather than be the lightest weakling around...
Additionally if you want to get to single digit bf.... dont cut to 150. Thats the hardest way to do it. At 150 legit single digit bodyfat requires you to have about 10-15 pounds of total fat... Good luck w leptin when you go that low. If you dont have great genes for leanness your body is not gonna give up what is semi essential bf until your really weak...
Or you can be closer to 200 where you can carry a healtheir amount of bf and still be single digits... i am able to stay single digit year round simply because i have some muscle not because i have extremely low levels of bf...
