I don't see how they cannot be effective. Don't use them because I'm a pretty heavy guy 200lbs, and I'm kinda scared puttin that weight on my dong. Any stretch is a good stretch.
If you have the time and privacy these stretches may be the best ADS you can do, definitely the cheapest. I attribute my 9" flaccid size to doing these. At one point I did these, in addition to the rest of my program, for up to 8 hours a day with circulation breaks every 15-20 minutes. As Still said there are more effective stretches but using these as a supplement to your routine is wise. They are very effective for increasing flaccid size.
True but there is a special place for Lazy Ass Stretches especially for those who sit all day. LAS will help cement a longer flaccid size, it is basically a teaching lesson to the penis, remain elongated! Since then things have changed and devices work so much better but for some Lazy Ass Stretches are al they can do due to financial hardship. In this case I always stress to take advantage of the monthly contest, free equipment is pretty cool.
