Squats: The King of All Exercises
The barbell back squat is the most effective lower-body exercise for building strength, muscle mass, and functional fitness. It trains the quads, glutes, hamstrings, and core in a single movement.
Proper Form
Set the bar in the rack at mid-chest height. Step under the bar, positioning it across your upper traps (high bar) or rear delts (low bar). Grip the bar outside shoulder width.
Unrack the bar by standing up, then take two to three steps back. Position your feet shoulder-width apart with toes pointed slightly outward at 15-30 degrees.
Take a deep breath, brace your core, and initiate the squat by simultaneously bending your hips and knees. Push your knees out over your toes.
Descend until your hip crease drops below the top of your knee (parallel or below), keeping your chest up and back tight.
Drive through your mid-foot to stand back up, exhaling past the sticking point. Lock out your hips and knees at the top.
Maintain a neutral spine throughout. If your lower back rounds (butt wink) at depth, address ankle mobility or reduce depth until flexibility improves.

Squats on GLP-1 Medications
The barbell squat is the single most important exercise for GLP-1 patients to preserve lower body muscle mass during weight loss. The squat recruits more total muscle tissue than almost any other exercise, triggering a powerful systemic anabolic response that helps counteract the muscle loss associated with calorie restriction. Studies show that resistance-trained individuals on GLP-1 medications retain significantly more lean mass than those who do not train. Start with bodyweight squats or goblet squats if you are deconditioned, and progress to barbell squats as strength improves.

Why Everyone Should Squat
The squat is a fundamental human movement pattern. Before chairs existed, humans rested in a deep squat position throughout the day. The barbell back squat is the loaded version of this natural movement, training the quadriceps, glutes, hamstrings, adductors, spinal erectors, and core stabilizers simultaneously. No other single exercise works as many muscles or produces as large a hormonal response. Research consistently shows that squatting builds more lower-body muscle mass than any combination of isolation exercises. Beyond muscle building, squatting improves bone density, joint health, mobility, balance, and athletic performance.
Squat Depth: How Low Should You Go?
Contrary to outdated advice, deep squats are not bad for your knees. In fact, stopping above parallel places more shear stress on the knee joint than squatting to full depth, because the hamstrings cannot assist the movement until the knee reaches roughly 90 degrees of flexion. Aim for at least parallel, where your hip crease is level with the top of your kneecap. Full-depth squats, often called ass-to-grass, provide the greatest muscle activation and range of motion but require adequate ankle and hip mobility. If you cannot reach parallel with a flat back, work on ankle mobility, hip flexor stretching, and use goblet squats to build depth gradually.
- Strength: 5 sets x 3-5 reps at 80-90% 1RM, 3-5 minute rest
- Hypertrophy: 3-4 sets x 8-12 reps at 65-75% 1RM, 90-120 second rest
- Beginner: 3 sets x 8-10 reps focusing on depth and form
Common Squat Errors and Fixes
Knee cave (valgus collapse) is the most dangerous squat fault. If your knees buckle inward during the ascent, reduce weight and cue yourself to push your knees out over your toes. Excessive forward lean typically indicates weak quads or poor ankle mobility. Heel elevation using squat shoes or small plates can help. Butt wink, where the pelvis tucks under at the bottom, usually results from limited hip or ankle mobility rather than a structural issue. Reduce depth slightly while working on mobility. Finally, rising hips with a stationary chest (the good-morning squat) means your back is doing the work your legs should be doing. Lighten the load and focus on driving your traps into the bar as you ascend.

Frequently Asked Questions
No, when performed correctly squats actually strengthen the muscles, tendons, and ligaments that support the knee joint. Research shows that squatters have thicker, healthier knee cartilage than non-squatters. Knee pain during squatting is usually caused by improper form, such as knee cave, rather than the squat itself. If you experience pain, consult a physical therapist to assess your movement pattern.
General strength standards: beginners should aim for bodyweight on the bar, intermediate lifters for 1.5x bodyweight, and advanced lifters for 2x bodyweight or more. These are guidelines, not requirements. Consistent progression matters more than hitting a specific number. Track your lifts and aim to add weight or reps each week.
Squats have a MET value of 5.0, burning approximately 6-7 calories per minute for a 180-pound person. Because squats recruit so much muscle mass, the post-exercise oxygen consumption (EPOC) effect is significant, meaning your metabolism stays elevated for hours after a heavy squat session. A full session of 5 working sets can burn 60-100 calories directly, with additional calorie burn afterward.
A lifting belt is beneficial when squatting at 80% or more of your one-rep max. The belt does not replace your core; it gives your abdominals something to brace against, allowing you to create higher intra-abdominal pressure and lift more safely. Train beltless at lighter weights to build raw core strength, and use the belt for heavier sets.
