Quit Randomizing Your Workout Order and Stick with Your Routine
Exercising is tough enough as it is, but if you're making a lot
of mistakes it's even harder. The Greatist tackles a few of the
biggest mistakes we tend to make, including random workouts, and
a lack of a routine.  A routine is important to help you keep
yourself on track, but as The Greatist points out, it's also
there so you learn exercises correctly and do programs that
actually work. If you find yourself working out in a random
order then it's probably time to step back, pick a program that
works, and stick to it. Don't randomly hit different machines or
do different exercises in any order you please. Pick an order,
and stick to it. You should keep your routine for a full two or
three months before switching it up. Head over to the Greatist
for a few more common mistakes, and how to fix them.  How to Fix
