Advanced Lower Body Workout: Squat Depth, Load, and Power
This session is built for advanced lifters who already move well under a barbell and are ready to push squat strength and lower-body power to the next level. If you've spent real time in the gym, understand how to brace and hinge, and want a structured, evidence-informed session that trains both maximal strength and explosive output, this one is for you. The future version of you — one who jumps higher, runs faster, and squats heavier — starts right here.
What the research says
Two themes from the research are worth knowing before you load up. First, complex training — pairing heavier strength work with lower-load explosive exercises in the same session — has been studied in a meta-analysis of 33 studies covering over a thousand athletes. CT produced clear improvements in jump height, squat strength, and sprint performance. When compared head-to-head with traditional training, CT came out ahead specifically for one-rep-max squat strength and 20-metre sprint time; for other measures the advantage over traditional methods was not statistically clear. Second, lower-body power — particularly jump ability — along with aerobic capacity together accounted for 81% of the variance in overall CrossFit competition performance in one study of 15 male amateur athletes, suggesting these qualities are meaningfully related to real-world athletic output.
The complex training meta-analysis is relatively strong — 33 studies, over 1,000 participants, random-effects model — but the head-to-head advantage over traditional training was significant only for two specific outcomes; the CrossFit study is a single small study (n = 15 male athletes) with correlational findings, so both should be interpreted with appropriate scope.
A meta-analysis of 33 studies (1,064 healthy participants) found that complex training — combining higher-load and lower-load exercises in one workout — produced significant improvements in countermovement jump height (95% CI 5.6–12.3%), squat jump height (95% CI 8.0–17.4%), one-repetition maximum squat performance (95% CI 16.4–30.7%), and sprint times across distances from 5 m to 30 m. When compared directly to traditional training, complex training showed superior effects only for 1-RM squat strength (95% CI 0.2–13.7%) and 20 m sprint time (95% CI −1.6 to −0.1%); differences on other measures were not statistically significant.

Significant correlations (r = 0.58–0.75, all p < 0.05) were also found between overall performance and jump ability, mean and peak power output on the Wingate test, relative maximum strength for the deep full squat and bench press, and VO₂max and speed on an incremental running test.

Warmup
Lie on your back, with one leg extended straight out. With the other leg, bend the hip and knee to 90 degrees. You may brace your leg with your hands if necessary. This will be your starting position. Extend your leg straight into the air, pausing briefly at the top. Return the leg to the starting position. Repeat for 10-20 repetitions, and then switch to the other leg.
Use a sturdy object like a squat rack to hold yourself. Lift the right leg in the air (just around 2 inches from the floor) and perform a circular motion with the big toe. Pretend that you are drawing a big circle with it. Tip: One circle equals 1 repetition. Breathe normally as you perform the movement. When you are done with the right foot, then repeat with the left leg.
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.
Main
This exercise is best performed inside a squat rack for safety purposes. To begin, first place a flat bench or a box behind you. The flat bench is used to teach you to set your hips back and to hit depth. Then, set the bar on a rack that best matches your height. 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 as looking down will get you off balance and also maintain a straight back. This will be your starting position. (Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances discussed in the foot stances section). Begin to slowly lower the bar by bending the knees and sitting your hips back as you maintain a straight posture with the head up. Continue down until you slightly touch the bench behind you. Inhale as you perform this portion of the movement. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that is perpendicular to the front. If your knees are past that imaginary line (if they are past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly. Begin to raise the bar as you exhale by pushing the floor with the heel 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.
Begin in a power rack with a box at the appropriate height behind you. Set up the bands on the sleeves, secured to either band pegs, the rack, or dumbbells so that there is appropriate tension. If dumbbells are used, secure them so that they don't move. Also, ensure that the dumbbells you are using are heavy enough for the bands that you are using. Additional plates can be used to hold the dumbbells down. If more tension is needed, you can either widen the base on the floor or choke the bands. 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. Use care to return the barbell to the rack.

To set up the chains, begin by looping the leader chain over the sleeves of the bar. The heavy chain should be attached using a snap hook. Adjust the length of the lead chain so that a few links are still on the floor at the top of the movement. Begin by stepping under the bar and placing it across the back of the shoulders.

This exercise is best performed inside a squat rack for safety purposes. To begin, first set the bar on a rack that best matches your height. Once the correct height is chosen and the bar is loaded, bring your arms up under the bar while keeping the elbows high and the upper arm slightly above parallel to the floor. Rest the bar on top of the deltoids and cross your arms while grasping the bar for total control. Lift the bar 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 as looking down will get you off balance and also maintain a straight back. This will be your starting position. (Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances described in the foot positioning section). Begin to slowly lower the bar by bending the knees as you maintain a straight posture with the head up. Continue down until the angle between the upper leg and the calves becomes slightly less than 90-degrees (which is the point in which the upper legs are below parallel to the floor). Inhale as you perform this portion of the movement. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that is perpendicular to the front. If your knees are past that imaginary line (if they are past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly. Begin to raise the bar as you exhale by pushing the floor mainly with the middle of your foot as you straighten the legs again and go back to the starting position. Repeat for the recommended amount of repetitions.

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.
From a lying position, bend your knees and keep your feet on the floor. Place your ankle of one foot on your opposite knee. Grasp the thigh or knee of the bottom leg and pull both of your legs into the chest. Relax your neck and shoulders. Hold for 10-20 seconds and then switch sides.
Set and rep ranges are general starting suggestions based on this guide's level — adjust to your own experience, and progress gradually.
This session involves heavy barbell loading and accommodating resistance — have a qualified spotter present for the squat variations, ensure collars are locked on all bar setups including band-anchored and chain-loaded configurations, and reduce load immediately if you notice any breakdown in spinal neutral or knee tracking; nothing here is medical advice, so consult a qualified professional before training if you have any existing lower-body injury or joint concern.
