Amazing splits include push/pull, push/pull/legs, and upper/lower splits. These splits allow you to gain a sufficient enough weekly volume without destroying your muscles in one single workout like you do in say a bro split.

The best split is the one you're going to stick to.

However, deploy the right below-the-belt moves and you’ll pump blood to your largest muscles, burning up the calories and toning your body from shoulders to calves. So which moves make leg day count the most?
