Even if you’re goals are just to be in regular awesome shape, rather than body building shape, I strongly recommend that you take a good look at this show and get an idea of what training with weights is supposed to look like.
Something I talk about a lot is that when training with weights, you should actually need to take that minute or two break in between sets. Especially on “power” movements as I call them in my program, where we are performing heavy, compound exercises. A lot of people just count through 10 (or however many) easy reps and really short change themselves of the results they should be getting. If the target is 10 reps, that means choose the heaviest amount of weight you can manage for 10 reps, and squeeze every ounce of energy out of the targeted muscle groups.
You’ll see a variety of approaches in this series but even when the athletes are just plodding through the routine as I like to do, you will see how hard you should be working and how exhausted you should be in between sets.
