Squats are a must if you want to build muscle in your glutes, quads, and hamstrings. Adding some muscle growth to this area as a woman accentuates your natural curves in a flattering way.
Pushups are one of the most effective upper body exercises you can perform without equipment. These will help tone up your arms and upper body while building strength.
They hit the glutes, hamstrings, and quads in a different way than squats, helping to ensure all the fibers in your lower body get the stimulus to build more muscle.
Glute bridges are the best way to specifically target your gluteus maximus, which is the muscle responsible for developing a defined, shapely posterior. Begin on your back with your feet on the ground and your knees bent.
Side lunges hit your exterior hip and thigh primarily, creating flattering curves on your hips when viewed from the front.
Side plank bridges are my favorite under-utilized core exercise. They focus on the obliques, deep core stabilizers, and outer hips for a complete "side body" toning exercise.
