Obviously, you can't resize your thighs, flatten your belly, and firm your butt—in just 5 minutes. But what you can do is add these simple shortcuts courtesy of Women's Heath will ensure that you're getting the most out of your workout:

1. Marching Glute Bridge

Start by lying face-up with knees bent and feet flat on the floor, before raising your hips to form a straight line from shoulders to knees:

1. Lift your right knee toward your chest.
2. Hold for two seconds; lower and repeat with your left leg. That's one rep.

2. Inverted Shoulder Press

Place your hands on the floor outside your shoulders and raise your hips so that your torso is nearly perpendicular to the floor:

1. From that position, bend your elbows to lower your body until your head almost touches the floor
2. Pause, then push back to start. That's one rep.

Quick Tip: Place your feet on a step or bench to increase the challenge.

3. Alternating Switch Lunge

Step your right leg forward and bend both knees to lower into a lunge:

1. Press through your right heel to return to standing, keeping your foot lifted, then immediately step your right foot back and lower into a lunge
2. Press through your left heel to return to standing. That's one rep.

Quick Tip: Make it easier by placing your foot on the floor each time you pass the starting position.

4. Skater Hops

Stand on your left foot with your left knee slightly bent and your right foot slightly off the floor:

1. Jump to the right and land on your right foot, bringing your left foot slightly off the floor That's one rep.
2. Jump to the left and continue alternating as quickly as possible.

5. Rotating T Extension

Start in a pushup position:

1. Keeping your arms straight and your core engaged, shift your weight onto your left arm while rotating your torso to the right.
2. Raise your right arm toward the ceiling so that your body forms a 'T'
3. Hold for three seconds, then return to start and repeat on the other side. That's one rep.

Quick Tip: Make it harder by adding a pushup every time you move from side to side.
