"Warmup? Pfff, What a Waste of Time!"

When you perform your resistance workouts, be sure you add in at least a "moderate to intense" 3-5 minute cardiovascular warm-up before hand. This helps prep the body for both burning calories and getting great lifts that your body will be "impressed" with!  Studies show that starting a workout off, whether cardio or resistance, more intensely rather than mild or moderate will cause a greater calorie burn through the entire workout.  The heart, lungs and vascular network can be thought of as our body's personal engine.  When that engine is primed, a greater efficiency and better performance is the result.  This goes pretty much for any athlete in any event, so then it most certainly goes for everyone else, barring any health limitations.

Next, you'll want to be sure, and this is strict, to get at least one good exercise specific warmup prior to the FIRST resistance exercise that you are to perform.  The reason for this is similar to the cardio warmup, yet it will  lend greatly in reducing the risk of injury! As a matter of fact, it may just determine whether or not we are to get injured on a given workout day.  As a bonus, the exercise specific warm-up also hyper-surges performance enhancing, oxygen carrying blood flow into the individual muscle fibers creating an optimal environment for our absolute best while also greatly reducing risk of injury to tendon and cartilage tissues! Basically, it's much more important than we typically realize. So, get those cells pumped full of blood before giving it your all! You'll not only get a better lift, you'll build more muscle through fiber tearing.
