The point of having a game plan is this: Once you get to the gym, you're more likely to push yourself hard if you are seeing the workout of the day. You won't accidentally forget to work a particular muscle. You are even less likely to lose the motivation than if you just walk into a gym and decide on the spot to do.
I just planned my workouts for the next four weeks by dividing each day into a muscle group or two. This way I know that I am targeting as many muscles as hard as I can throughout the week. I have a really strong chest, so I love to sit at my beloved bench press as much as possible when in reality, I have no need for strong pecs when my super weak back muscles get neglected. For me, bench press isn't really even a functional exercise so you'll notice that I don't even do it anymore and that I work that area by push ups and dumbbell incline chest press because it works my shoulders a little as well. I try to either change my weight lifting program completely or increase the weight every 4-6 weeks. However, if I'm not sore the next day, the weight goes up for the next week. I love being sore everyday because I know that I'm working hard and getting results that I want.
I got sick of rewriting workouts everyday and flipping through my notebook that is all tattered from being in my gym back and usage that I decided to get some big note cards and laminate them. They now have a super easy way to laminate where it's all pre-cut and you just pull the sticker part off and press the sides together. Now I have a much more durable workout list that I'm not writing on all the time. The only disadvantage that I've come across is that I can't make edits on weight or reps, so I guess I'll keep my notebook in my bag in case that situation were to arise.
Even though I have some modifications to the plan right now because of a broken ankle, here's my week: (Please note that some of these are machines so my weight is based on that particular machine and its resistance)
