Intermediate Quad Workout: Build Strength and Size in Your Front Thighs
This session is built for intermediate lifters who have a solid foundation with barbell movements and want to add real size and strength to their quads. Whether you're chasing bigger legs, better performance in sport, or simply want squats to stop feeling like your weak point, this workout meets you where you are. We'll walk you through everything — from warm-up to cooldown — so you can train hard and walk out feeling like you actually accomplished something.
What the research says
A handful of well-designed studies give us a clear picture of how to train quads effectively. The biggest takeaway is that depth matters: squatting through a full range of motion produced significantly greater gains in front thigh muscle size and strength than shallow squats. On top of that, both increasing your load over time and increasing your reps over time drove similar hypertrophy and strength gains — meaning you have real flexibility in how you push your sessions forward. And when it comes to exercise variety, a 10-week study found that rotating through different lower-body exercises each session produced similar muscle and strength gains compared to sticking with the same two movements every session. The evidence points toward squatting deep, staying consistent with progressive challenge, and not overthinking your exercise rotation.
Moderate to strong for the core findings — the range-of-motion and progressive overload studies are reasonably well-controlled, though sample sizes are small and study durations are relatively short; the exercise variety finding is consistent across its 10-week trial but also limited to one population.
A 12-week study compared deep squats (0–120° of knee flexion) to shallow squats (0–60° of knee flexion) in male students. The deep squat group showed significantly greater increases in front thigh muscle cross-sectional area (4–7% more than the shallow squat group), greater isometric knee extension strength at 75° and 105° of knee flexion, and greater squat-jump performance (15 ± 3% more than the shallow squat group).
View study →An 8-week study in resistance-trained individuals compared two approaches to progressive overload: increasing load while keeping repetitions constant versus increasing repetitions while keeping load constant. Both groups performed four sets of four lower-body exercises twice per week. Between-group differences in quadriceps muscle thickness and lower-body strength were not significant, indicating that progressively increasing reps produced similar muscular adaptations to progressively increasing load over the study period.
View study →A 6-week study in healthy women compared barbell squat training with 'knees in' versus 'knees out' tibiofemoral alignment. Both groups significantly increased lower-body strength and vasti (quad) muscle volume. No muscles with a hip extensor action increased in size in either group. Gluteus maximus volume decreased in the 'knees in' group, though the study noted the direction of loading change this reflects is unclear. Self-reported knee health scores did not differ between groups or change over time.
View study →A 10-week study in young women compared performing the same two lower-body exercises each session (constant group) versus rotating through three different exercise pairs across the week's sessions (varied group). Both groups increased muscle thickness of the thigh's anterior, lateral, and posterior aspects, as well as 1RM strength, to a similar degree, with no statistically significant differences between groups.

Warmup
Stand with your hands behind your head, and squat down keeping your torso upright and your head up. This will be your starting position. Jump forward several feet, avoiding jumping unnecessarily high. As your feet contact the ground, absorb the impact through your legs, and jump again. Repeat this action 5-10 times.
Lie face down on the floor, with your arms extended out to your side, palms pressed to the floor. This will be your starting position. To begin, flex one knee and bring that leg across the back of your body, attempting to touch it to the ground near the opposite hand. Promptly return the leg to the starting postion, and quickly repeat with the other leg. Continue alternating for 10-20 repetitions.
Lay face down on the floor with your partner kneeling beside you. Flex one knee and raise that leg off the ground, attempting to touch your glutes with your foot. Your partner should hold the knee and ankle. This will be your starting position. Attempt to extend your knee while your partner prevents any actual movement. After 10-20 seconds, relax your muscles as your partner gently pushes the foot towards your glutes, further stretching the quadriceps and hip flexors. After 10-20 seconds, switch sides.
Main
This exercise is best performed inside a squat rack for safety purposes. To begin, first set the bar on a rack just above shoulder level. Once the correct height is chosen and the bar is loaded, step under the bar and place the back of your shoulders (slightly below the neck) across it. Hold on to the bar using both arms at each side and lift it off the rack by first pushing with your legs and at the same time straightening your torso. Step away from the rack and position your legs using a shoulder-width medium stance with the toes slightly pointed out. Keep your head up at all times and maintain a straight back. This will be your starting position. Begin to slowly lower the bar by bending the knees and sitting back with your hips as you maintain a straight posture with the head up. Continue down until your hamstrings are on your calves. Inhale as you perform this portion of the movement. Begin to raise the bar as you exhale by pushing the floor with the heel or middle of your foot as you straighten the legs and extend the hips to go back to the starting position. Repeat for the recommended amount of repetitions.
Stand up straight while holding a barbell behind you at arms length and your feet at shoulder width. Tip: A shoulder width grip is best with the palms of your hands facing back. You can use wrist wraps for this exercise for a better grip. This will be your starting position. While keeping your head and eyes up and back straight, squat until your upper thighs are parallel to the floor. Breathe in as you slowly go down. Pressing mainly with the heel of the foot and squeezing the thighs, go back up as you breathe out. Repeat for the recommended amount of repetitions.

Hold on to the bar using both arms at each side and lift it off the rack by first pushing with your legs and at the same time straightening your torso. Step away from the rack and step forward with your right leg and squat down through your hips, while keeping the torso upright and maintaining balance. Inhale as you go down. Note: Do not allow your knee to go forward beyond your toes as you come down, as this will put undue stress on the knee joint. li> Using mainly the heel of your foot, push up and go back to the starting position as you exhale. Repeat the movement for the recommended amount of repetitions and then perform with the left leg.
Stand up straight while holding a barbell placed on the back of your shoulders (slightly below the neck) and stand upright behind an elevated platform (such as the one used for spotting behind a flat bench). This is your starting position. Place the right foot on the elevated platform. Step on the platform by extending the hip and the knee of your right leg. Use the heel mainly to lift the rest of your body up and place the foot of the left leg on the platform as well. Breathe out as you execute the force required to come up. Step down with the left leg by flexing the hip and knee of the right leg as you inhale. Return to the original standing position by placing the right foot of to next to the left foot on the initial position. Repeat with the right leg for the recommended amount of repetitions and then perform with the left leg.
The box squat allows you to squat to desired depth and develop explosive strength in the squat movement. Begin in a power rack with a box at the appropriate height behind you. Typically, you would aim for a box height that brings you to a parallel squat, but you can train higher or lower if desired. Begin by stepping under the bar and placing it across the back of the shoulders. Squeeze your shoulder blades together and rotate your elbows forward, attempting to bend the bar across your shoulders. Remove the bar from the rack, creating a tight arch in your lower back, and step back into position. Place your feet wider for more emphasis on the back, glutes, adductors, and hamstrings, or closer together for more quad development. Keep your head facing forward. With your back, shoulders, and core tight, push your knees and butt out and you begin your descent. Sit back with your hips until you are seated on the box. Ideally, your shins should be perpendicular to the ground. Pause when you reach the box, and relax the hip flexors. Never bounce off of a box. Keeping the weight on your heels and pushing your feet and knees out, drive upward off of the box as you lead the movement with your head. Continue upward, maintaining tightness head to toe.
Cooldown
Start off on your hands and knees, then lift your leg off the floor and hold the foot with your hand. Use your hand to hold the foot or ankle, keeping the knee fully flexed, stretching the quadriceps and hip flexors. Focus on extending your hips, thrusting them towards the floor. Hold for 10-20 seconds and then switch sides.
Lie face down on the floor, with a rope, belt, or band looped around one foot. Flex the knee and extend the hip of the leg to be stretched, using both hands to pull on the belt. Your knee and your hip should come off of the floor, creating tension in the hip flexors and quadriceps. Hold the stretch for 10-20 seconds, and repeat on the other leg.
Set and rep ranges are general starting suggestions based on this guide's level — adjust to your own experience, and progress gradually.
