1. Instead of doing a million crunches, focus on just two expert-recommended moves.
2. Combine your cardio and strength routines into one workout.
3. Make couch time a little more active with an easy-does-it workout.
4. Introduce your butt to two beginner-friendly glute exercises you can do at home.
Glute bridges (above left) and hip thrusts (above right) come highly recommended by the experts for anyone who wants to work their butt. They're especially great if you spend lots of time sitting. You can do them at home with just your bodyweight or add weights to make them even more challenging.
