Never looked at it that way. I don't feel as if I am overtraining but it is time to change it up. I weighed myself before I started 3-AD, again 2 & 3 weeks in and no gain there. I tend to stay away from the scale as much as possible due to the illusion of gain from water weight. My workout log is my best friend, my family tells me I am getting bigger all of the time, haven't measured in a while, but I do take random photos in defferent poses. I see now that I was expecting freakish gains from 3-AD but really all I need is a slap in the face! This is a life long goal, I sometimes need a reminder to slow down.
lol - I hear ya, man!!! Not that I want to downplay any expectations or negate your feelings at all, but we always have to be realistic. There are many who believe that supplements of all varieties are the magical little pills and potions to make you huge quick. They aren't, but they do give you that extra little edge to push further, go faster longer, and make it through where you struggled on your own. The work is what counts, followed by diet, then rest, and then maybe supplements. Though many see others' progress and expect something similar to happen to them, few realize that we are all so very different in our histories, genetics, training capactiy and style, diet, and overall environment that it's about impossible for you to do the same as me, or vice versa.
But, to the good here, it does sound like you have made progress!! Family telling you that you look different is always an ego boost. Snapping photos is great. The scale? Eh... It's there, but even gravity changes around the world to some degree! Different folks experience things a bit differently. If you strength hasn't gone up, the scale has been the same, but you are looking and feeling harder and more defined, then that's just progress, my friend!! If you program is stale, perhaps it's time to change. Training as frequently as you do would, to me, be training for definition and stamina, rather than just brute size. Personally, with the frequency that I typically train, size is my goal as I could care less about having 6-pack abs. But for you, it's all in what you want out of it. Train wise, and never underestimate the power of research and planning!
And you're definitely right on one thing. This whole thing is about the journey, not just the destination. Have a goal in mind and reach for it. If you miss, then keep reaching! That whole saying about stopping to smell the roses is definitely true, and definitely worth it.
