Lower body exercises are any movements that primarily work the muscles from your hips down to your feet, including your glutes, quadriceps, hamstrings, and calves. These muscle groups are the largest in your body, and training them builds the foundation for nearly everything you do on your feet, from walking upstairs to sprinting to picking something heavy off the ground.
The exercises fall into two broad categories: compound movements that work multiple joints and muscle groups at once, and isolation movements that zero in on a single muscle. A well-rounded lower body routine uses both.
Muscles You’re Training
Your lower body contains four major muscle groups, each responsible for different movements. Your quadriceps, a set of four muscles running down the front of your thigh, handle knee extension and help stabilize your body during balance. Your hamstrings run down the back of your thigh from just under your glutes to either side of your knee, and they pull your leg backward and rotate it at the hip. Your glutes, the largest muscles in your body, drive hip extension: standing up, climbing, pushing off into a run. Your calves, made up of two muscles called the gastrocnemius and soleus, flex and point your toes, power your jumps, and help you maintain posture by stabilizing your lower legs.
Together, the glutes, hamstrings, and calves form what’s often called the posterior chain, the connected line of muscles along your backside. The posterior chain also includes smaller stabilizers around the lower spine. These muscles work as a unit whenever you get up off the floor, lift a heavy object, or run, so training them together matters as much as training any single muscle in isolation.
Compound Exercises
Compound movements recruit multiple muscle groups through more than one joint, which means you can load them heavier and get more work done per rep. These should form the core of any lower body program.
- Barbell squat: The most fundamental lower body exercise. It primarily targets your quads and glute max through a deep bending of the hips and knees. Going through a full range of motion matters here. Partial reps let you use more weight, but they don’t build more muscle. Legs grow best when trained through the stretched position.
- Deadlift: Primarily works your hamstrings and glutes. You lift a barbell from the floor by driving your hips forward, which loads the entire posterior chain heavily.
- Romanian deadlift: A variation where you hinge at the hips and lower the bar only to about mid-shin, keeping your legs relatively straight. This shifts more emphasis onto the hamstrings and glutes compared to a conventional deadlift, because you’re holding tension in the stretched position longer.
- Lunge: Targets your quads and glutes while also demanding balance and coordination. Reverse lunges, where you step backward instead of forward, place extra emphasis on the glute max and tend to be easier on the knees.
- Leg press: A machine-based alternative to squats that targets the same muscles (quads and glutes) with less demand on your core and balance. Useful for adding volume without fatiguing your lower back.
- Hip thrust: Isolates the glutes more directly than any other compound movement. You drive a loaded barbell upward by squeezing your glutes at the top of each rep, with your upper back supported on a bench.
Isolation Exercises
Isolation exercises target one muscle group through a single joint. They’re useful for bringing up a lagging muscle, adding volume without taxing your whole body, or working around an injury.
The leg extension is the standard quad isolation exercise, with minimal involvement from any other muscle group. You sit in a machine and extend your knees against resistance. On the opposite side, the leg curl isolates the hamstrings by having you bend your knee against resistance while lying face down or seated.
For calves, seated and standing calf raises hit different parts of the muscle. The seated version predominantly works the soleus (the deeper calf muscle), because your knee is bent. The standing version shifts the load to the gastrocnemius (the visible outer calf muscle), because your legs are straight. Using both gives you more complete calf development.
Single-Leg Training
Most people have one leg that’s stronger than the other. Bilateral exercises like squats and deadlifts can mask that imbalance because the stronger leg compensates. Single-leg (unilateral) exercises force each side to work independently, which builds more balanced strength and reduces injury risk.
A meta-analysis published in Frontiers in Physiology found that unilateral training can produce greater strength gains than bilateral training alone. It also found that single-leg work improves jumping ability in two-legged patterns, likely because reducing the imbalance between sides lets both legs contribute more evenly to explosive movements.
The most effective single-leg lower body exercises include Bulgarian split squats (rear foot elevated on a bench behind you), single-leg Romanian deadlifts, step-ups, and single-leg squats. Bulgarian split squats are particularly valuable because they hit your quads, glute max, and even the smaller glute muscles that stabilize your hip.
How Often and How Much
The American College of Sports Medicine recommends resistance training all major muscle groups at least twice per week with high effort. For building strength specifically, the evidence points to lifting at or above 80% of your one-rep max, through a complete range of motion, for at least 2 to 3 sets per exercise. For building muscle size, higher weekly volume matters: at least 10 sets per muscle group per week, with diminishing returns kicking in around 18 to 20 weekly sets.
In practical terms, this means training your lower body across two or three sessions per week rather than cramming everything into one brutal “leg day.” Spreading the volume across multiple sessions lets you train with higher quality effort each time.
Making Progress Over Time
Your muscles adapt to a stimulus, so the same weight for the same reps eventually stops producing results. Progressive overload, gradually increasing the challenge, is what drives continued strength and muscle gains. But adding weight isn’t the only way to do this.
You can progress by adding reps within your current weight, adding an extra set once you can complete all reps with clean form, slowing down the lowering phase of each rep to 2 to 4 seconds, or shortening your rest periods between sets. All of these increase the total demand on your muscles.
When you do add weight, a jump of 2.5 to 5 kilograms per week is a sustainable rate for most lower body exercises, provided you’re completing all your reps with good form first. A useful framework: if you can hit the top of your target rep range across all sets, it’s time to increase the load. So if you’re squatting 60 kilograms for 3 sets of 10 and all 30 reps feel controlled, bump it to 62.5 kilograms next session. If your reps drop, stay at that weight until they come back up.
Common Form Mistakes
The two most frequent errors in lower body training are cutting range of motion short and letting technique break down under heavy loads. Half-rep squats and Romanian deadlifts let you use more weight on the bar, but they produce less muscle growth than full-range reps at a lighter load. Your muscles experience the most growth stimulus in the stretched position, which is the bottom of a squat and the lowest point of a Romanian deadlift. Stopping short of that position leaves results on the table.
On squats, the most common breakdown is the knees caving inward as you stand up, which shifts stress onto the ligaments rather than the muscles. On deadlifts, it’s rounding the lower back, which loads the spine instead of the glutes and hamstrings. Both issues typically come from using more weight than you can control. Dropping the load by 10 to 20% and focusing on smooth, controlled reps through a full range of motion will produce better long-term results than grinding out sloppy heavy sets.
