What? Do you really think an exercise like bench press can only be applicable to motion in the same plane it is done in? Obviously the pectoral muscles will work pushing something away from you standing up as well. In fact, the pecs have significant deltoid movement responsibility as well. Did you think the pecs only worked lying down? And pushups, which you advocate, are the same motion flipped around so how are they any more natural in your opinion? The body position in both exercises is to allow for the application of gravity to the weight being moved so as to be effective.
Although the debate rages on (and probably always will) there is a controversial solution for getting the best of both worlds, and that involves using both compounds together in a cycle. Although both of these oral compounds are liver toxic, you can use them safely at moderate doses during short cycles and alongside a liver protectant supplement. The most common Anadrol Dianabol stack involves a 4-6 week cycle during which you take 25mg of Dianabol and 50mg of Anadrol per day. The synergistic effects are quite noticeable at these doses. In short, using the two together counteracts many of the side effects due to the low doses of each, including appetite loss, aches and pains, and even fatigue.
