A lot of interesting workouts here. Most of them involving bars - which I'm not a huge fan of. I started focusing on pure bodyweight calisthenic routines in the summer, and finally settled on one that seems to fit me in December. I'm up to almost two months working off of the plan set down in a book called Convict Conditioning. It's a nice program that has the nice benefit of set-in-stone finishing goals, as well as readily defined steps to achieve those goals. This gives you short term satisfaction, and at the same time a very-long-term finishing point to keep your eyes on. The book revolves around six core exercises.
Single leg deep squat
Single arm pushup (and not that BS with your leg way out to the side)
Single arm pullup (again, not uneven pullups, although they are a step along the way)
hanging straight leg raise
single arm handstand pushup
Each of the six has ten steps to achieving the master exercise. So you're not starting out trying to knock out those six, you're progressing - spending minimum 5 weeks on each step. In the case of some steps (for example: diamond handstand pushup) you spend up to 18 weeks getting it perfect.
The reason I've eschewed work with bars is because they aren't natural movements. I have nothing against working with dumb-bells but the bars force your body to do things that it wouldn't do naturally. Each of the steps in the CC progressions focuses on natural movements that will give you strength through the tendons that will strengthen your joints - unlike bar work which causes more deterioration in the joints. An example would be the shoulder - many strength athletes will tell you the only solution to shoulder pain is to learn to live with it. This is a horrible way to look at it, but it is common. And it has nothing to do with them being strength athletes, working with heavy weights. If your workouts are doing anything but gradually lessening the pain in your life you're doing something very wrong.
Lets look at the presses - proper form for a press, bench and military as my examples, requires you to flare your elbows out, right? Proper form has your elbows out, lining you up with the bar to activate the major muscles involved (side heads of the delts and pectorals, respectively). A full range of motion is usually advised as well. Right? All the way down to the chest and back up. Now place that next to most natural motions you do every day. How many motions require you to splay your elbows way out? Imagine a father lifting a child, are the elbows way out or are they positioned in front of the body? Ask someone to hold something over their head. Are the elbows splayed out? Again, nope. Same goes for bringing the bar to the chest. Are we meant to do this? No way! Go to push someone away from you, go to push a car... do you start with your weight directly applied to your chest? Not a chance. All you're doing with "proper" bar exercise form is creating a situation that invites chronic injuries.
Guys, we on this forum are disc golfers. So to make this relate to you I give you this: the rotator cuff. We use that baby, we need it to crush. Am I right? Well guess what: it is especially prone to injury when placed under load with the humerus strongly twisted. What does proper form with bar exercises do to the humerus? Places a heavy load on it whilst exaggerating a twisting motion. Ask anyone that has dealt with serious shoulder injury - moving to dumb-bells and away from bars allows them to frequently continue to work with heavier weights they can no longer touch with a bar as they recover. Because the elbows are free to move naturally, the shoulders are free to move naturally. No more unnatural twisting. Additionally - the dumb-bells, because of the location of the plates, don't allow you to lower the "bar" to your chest, instead you're lowering the edge of those plates to your chest. A little less strain on the shoulders can go a long way.
Now going to pure bodyweight work, as I have, may be an extreme step. But if you want to stay healthy and keep your body ready to rip a disc, I highly recommend moving away from bar presses. It simply doesn't make sense for people that use their arms as we do.
