4. Grasshopper
This exercise targets the buttocks and hips and makes them firmer and more toned. It also strengthens the spine and upper body. Begin by lying on your stomach with your chin on the floor. Place your arms at your sides and make fists. Stretch out your legs and feet as much as you can without feeling uncomfortable. Then, slowly raise your legs one at a time while breathing in. Lower them again while breathing out. As this pose can be rather difficult, you should do a few stretches before trying this.
