Discover four excellent machines to enhance your quads!
Each muscle can be strengthened with free weights like barbells and dumbbells, or exercise machines, but quads particularly benefit significantly from the latter. Whether in your personal gym or a commercial fitness center, people often overlook the effectiveness of gym machines. However, if you observe those with the most substantial legs, or contestants at Mr. Olympia, there’s a 100% likelihood they incorporate machines into their routine.
Interestingly, gym culture frequently criticizes the use of machines for leg development. Many would rather stick to barbells than target their quads on a machine. They argue that “Machines aren’t as masculine” or “Machines lack functionality.” While the squat rack is undeniably effective for gains, machines provide an unparalleled muscle engagement experience.
Machines are incredible, and if you’re tired of having underdeveloped quads, get ready to use the following devices.
1 – The Hack Squat
The hack squat is a phenomenal machine due to its design that suits everyone’s physique. It was a favorite of the iconic bodybuilder Tom Platz, famed for his intensely rigorous leg workouts and possessing some of the most impressive legs globally. Therefore, you know it’s effective.
A hack squat is angled for a reason, unlike traditional barbell back squats where the bar sits on your back and you’re combating weighted gravity. The bar must remain over your center of mass; otherwise, you’d tip over, becoming a gym mishap.
To maintain balance, your joints bend at specific angles based on your physique. For some individuals, this results in a more vertical posture, leading to increased knee flexion (knee bend), and consequently, more significant quad growth.
However, individuals with less favorable limb proportions might not experience the same quad development, despite lifting the same weight and performing the same reps, due to anatomical limitations on knee flexion. The hack squat addresses this issue. The machine ensures stability and positions you at an angle to maximize knee flexion. It’s advised to place your feet slightly lower and closer if it encourages more knee flexion. While this isn’t universal, the hack squat often exceeds barbell back squats in building quads.
For optimal hack squat performance, follow these cues:
- Press through your entire foot.
- Allow your knee to move forward.
- Keep your back neutral against the pad with no posterior pelvic tilt.
- Hold the handles firmly for stability.
I personally prefer setting up a reverse band on hack squats to increase resistance at the top of the lift. This is gentler on the joints and makes the entire rep more challenging, not just the bottom portion.
2 – The Leg Press
The leg press is a bodybuilding staple and for good reason, but many gym users misuse it to satisfy their ego. Most people load too much weight and perform a limited range of motion, which is not ideal for muscle growth. Optimal gains require a full range of motion.
The leg press, used correctly, can fast-track your quad development. Here’s how to maximize quad growth with this machine.
Setup
Begin by setting the seat as far back as possible. This reduces hip flexion and glute stretch, enhancing your range of motion and increasing knee flexion. Less hip flexion and more knee flexion target the quads more effectively with less glute involvement.
To clarify, the glutes will still be active, but they’re not the main focus in this workout.
Keep your back pressed against the pad and, similar to the hack squat, avoid any posterior pelvic tilt. This maintains tension on the targeted muscles and, while it’s not particularly dangerous, reduces joint stress.
Your foot position should be comfortable. Consider a slightly narrower and lower stance for more quad activation, provided it doesn’t compromise your range of motion.
Warm-Up
Given the heavy load of the leg press, it’s wise to perform at least a couple of warm-up sets. This helps you find your groove and adjust your foot position as needed. Execute all warm-up sets precisely as you would your working sets.
This means maintaining a controlled eccentric, a powerful concentric, and a full range of motion, especially at the bottom position where the muscles are stretched, generating significant muscle-building mechanical tension.
As you add weight to your warm-up sets, ensure the range of motion is not compromised. If it is, you’ve added too much weight.
Working Sets
Before starting your working sets, you can add bands for accommodating resistance. If not accessible, it’s fine. Take a full rest before beginning your working set.
Brace every rep and push until you almost reach failure. Rest for at least 3 minutes between sets. If you feel capable of going with less rest, you likely didn’t push hard enough. By the third set, walking should be challenging. It’s okay; your quads will thank you once you replenish them.
Remember, the leg press utilizes a fixed plane. There’s no room for cheating the technique besides range of motion. Either your quads get stronger, or they don’t.
3 – The Smith Machine
When the leg press or hack squat is occupied, turn to the smith machine for excellent quad development. Indeed, the most criticized apparatus is one of the most effective tools in the gym for enhancing your leg muscles. Icons like Jay Cutler, 4-time Mr. Olympia, have been seen intensively working their legs on a smith machine.
“But it follows a fixed bar path.”
Exactly, that’s the advantage. That’s where all the perks originate. Comparable to a hack squat, the configuration of the smith machine enables you to achieve greater knee flexion through a more comprehensive range of motion.
“But the smith machine reduces stabilizer activity.” That’s precisely what makes the smith machine invaluable. Without placing great effort on your core to stabilize, you can intensely target your quads. You’re not constrained by core or stability demands, and it’s also gentler on your joints and nervous system. In essence, more muscle growth for less fatigue cost. A definitive advantage.
The smith machine also places you in the same stance as the bottom of a lunge, except both legs are involved, making it a symmetrical movement. Hence, it’s entirely functional. Critics need to reconsider their stance.
For a smith machine squat, you can position yourself directly beneath the bar or slightly ahead for increased knee flexion. If utilizing an angled smith machine, ensure you face the machine in the direction where the bar descends towards your front.
To execute each repetition, lower yourself smoothly as the bar glides down with control. Maintain an upright posture, pushing your knees forward. Descend into the squat as deeply as possible without allowing your back to round or your hips to tuck under.
Your quads should experience a significant stretch at the bottom, surpassing 90 degrees. Due to the fixed bar path and minimal stability requirements, training near or to complete failure will ensure thorough fatigue of all quad muscle fibers.
4 – Leg Extensions
The leg extension is the gem of machines. Its uniqueness is often overlooked. All devices mentioned so far are excellent, yet they resemble each other and free weight exercises concerning the muscle length they target.
All squat or compound quad movements work the quads in the extended position. To maximize muscle growth, you must train at all muscle lengths. Leg extensions are the sole exercise that targets the quads in the contracted position. Additionally, it’s among the few exercises that effectively engage the front of the quads (rectus femoris).
The rectus femoris is trickier to engage than other quadricep muscles because it spans both the hip and knee joints. Any squat or lunge exercise doesn’t place much mechanical strain on it.
Moreover, leg extensions cause minimal fatigue compared to compound leg movements. You can perform higher volume and incorporate it into high-frequency training programs without recovery concerns.
It also allows training to failure without risk of injury and the use of set-extending methods like myo-reps or rest-pause.
To set up, adjust the seat back as far as possible to maximize quad stretch, enhancing force production. Don’t position it too far back to maintain stability. Place the pad above ankle level. Use a seat belt if available and grip the handles firmly. Your forearms should exert notable force to pull yourself into the seat, keeping your body stable for smooth quad force output.
Kick upward forcefully while maintaining stability. Pause for a full second with your knees fully extended and lower with controlled movements, especially towards the bottom where resistance lessens.
Avoid slamming your leg down as it reduces tension in the stretched position, crucial for the growth of the rectus femoris.
Quad Training Conclusion
Machines offer numerous benefits, including optimal biomechanics, stability, and force output, allowing you to train your quads effectively. It’s quite challenging to build your quads quickly and naturally without machines.
These machines have excessive advantages for expanding your thighs. So reconsider before dismissing machines as ineffective.
Indeed, machines enable the targeted muscle to approach near failure. They’ll burn intensely. Are you tough enough to withstand it? If so, your quads will flourish.
