I posted earlier on my routines and how I structure them. I also mentioned that I despise a lot of what I read about routines because I feel like they sound like directions for assembling a grill. They don't take into account that we are all built differently. We have different physical abilities and attributes. Take a biceps muscle and move the insertion and origion movements farther away from the joints and you have a person who is capable of great power but not precision. Some people are the opposite. This is just one example of the differences in body composition.
There's other considerations too. Let's say you take someone's routine that takes 45 minutes to do. What happens if you only have fifteen minutes? Are you better off to bag working out rather than figuring out a way to work out with some effectiveness? Let's throw in a weakness in the body, such as an injury. Let's say you can't do a pushup because your elbow is swollen. Should you skip or work around it, such as doing a hands-wide pushup? Well, that wasn't in the routine. Does it matter?
You are not a cookie-cutter creation. Don't workout like you are. You can get something out of any routine that you chose to do if you apply hard work and mental focus on your efforts. I'll concede that routine A may be better than routine B but if B is all you can do or what you like to do and you are moving your body, who am I to say? I'd rather you do something than nothing. That's my mantra when I exercise. It should be yours too.
