That routine that you 'read somewhere' was talking a few lies. 1 inch plus in 5 weeks with a one on, one off approach is bull. That's 20 sessions. You may gain 0.25 of an inch considering you're new. Half an inch at a stretch. If you didn't take days off you'd be better off, considering it's not a very hard routine, i'd say the newbie one is harder, time wise, as it involves kegels, testicle health and probably more directions than the one you 'read somewhere'.
Remember than this isn't a quick 5 inch turn around where you can knock your 6 inch up to a 7 and go on your merry way with Penis Enlargement as an after thought. Even if you gained 1 inch in 5 weeks, you'd need to cement the gains, probably taking another 2 months. It takes dedication and commitment.
