Building jacked and super strong legs isn’t just about aesthetics – it’s also vital for functional strength, athletic performance, and injury prevention. To get the best results, you need a combination of compound movements, single-leg exercises, and isolation work. This guide outlines the top 10 exercises for developing powerful legs, with an emphasis on how each one works, what makes it effective, and the science behind it.

1. Barbell Back Squat

The barbell back squat is often called the “king of leg exercises” – and for good reason. This compound movement targets the quads, hamstrings, glutes, and even the lower back and core. The squat is crucial for building muscle mass and strength due to the sheer volume of muscle recruitment. According to a study published in the Journal of Strength and Conditioning Research, squatting with heavy loads produces greater activation in the quadriceps and gluteus maximus than lighter loads, emphasising the importance of progressive overload (Clark, Lambert, & Hunter, 2012).

Barbell back squats also enhance functional fitness. By engaging the core and stabilising muscles, squats transfer directly to improved performance in other athletic activities. Research shows that the back squat improves vertical jump, sprinting ability, and overall leg power (Wisløff, Castagna, Helgerud, Jones, & Hoff, 2004).

2. Romanian Deadlift

The Romanian deadlift (RDL) is one of the best posterior chain exercises, targeting the hamstrings, glutes, and lower back. It’s a hip-hinge movement that stretches and strengthens the hamstrings in their elongated position, which is particularly beneficial for building eccentric strength. A study in the Journal of Electromyography and Kinesiology found that the RDL activates the hamstrings more than any other leg exercise, making it essential for anyone looking to strengthen the back of their legs (Bourne et al., 2017).

Additionally, Romanian deadlifts are excellent for improving flexibility and mobility in the hamstrings. They also help to balance out muscle imbalances, particularly for individuals who are quad-dominant.

3. Bulgarian Split Squat

The Bulgarian split squat is a unilateral (single-leg) exercise that challenges the quadriceps, glutes, and hamstrings while also improving balance and core stability. This exercise not only helps prevent strength imbalances between legs but also enhances stabiliser muscle activation, reducing the risk of injury. A study published in the Journal of Sports Science and Medicine compared the effects of bilateral and unilateral training, finding that unilateral movements like the Bulgarian split squat significantly increase lower body strength and stability (McCurdy et al., 2005).

Another key benefit of Bulgarian split squats is their ability to work the glutes in a stretched position. This stretch under load promotes hypertrophy and strength gains in the gluteal muscles, making it a great exercise for anyone seeking stronger and more muscular legs.

4. Front Squat

The front squat shifts the load to the front of the body, placing greater emphasis on the quadriceps than the back squat. It also requires more core and upper body strength to maintain an upright torso. A study in the Journal of Strength and Conditioning Research showed that front squats place less compressive forces on the knee joint compared to back squats, making them a better option for individuals with knee issues (Gullett et al., 2009).

The upright posture of the front squat engages the core and spinal erectors more than back squats, offering a dual benefit for both leg and core development. This makes front squats an excellent choice for those looking to maximise quad activation while improving posture and spinal stability.

5. Nordic Hamstring Curl

The Nordic hamstring curl is a bodyweight exercise that targets the hamstrings through eccentric contraction. This movement is known for its ability to strengthen the hamstrings and prevent injury, particularly in athletes. According to a study published in the British Journal of Sports Medicine, the Nordic hamstring curl reduces the risk of hamstring strains by up to 51% when incorporated into regular training (Petersen et al., 2011).

Eccentric strength is crucial for preventing injury, especially in sports that involve sprinting or rapid deceleration. The Nordic hamstring curl places a high demand on the hamstrings during the lowering phase, helping to build strength and resilience in the muscle.

6. Walking Lunges

Walking lunges are a functional exercise that targets the quadriceps, hamstrings, glutes, and calves while also improving balance, coordination, and mobility. This movement also promotes muscular endurance and strength through the constant shifting of body weight and stabilisation required. A study in the Journal of Applied Biomechanics found that walking lunges engage more muscle fibres in the glutes and hamstrings than stationary lunges, making them a superior variation for lower body strength and hypertrophy (Madigan, Pidcoe, & John, 2013).

Walking lunges can be easily modified by adding dumbbells or a barbell, increasing the intensity and resistance for further muscle development.

7. Step-Up

Step-ups are another unilateral movement that emphasises the quadriceps and glutes, while also recruiting stabiliser muscles in the core and hips. This exercise mimics everyday functional movements like climbing stairs or hiking, making it a valuable addition to any leg training routine. According to a study published in the Journal of Sports Rehabilitation, step-ups are highly effective for improving quadriceps strength, particularly in individuals recovering from knee injuries (Escamilla, Macleod, & Wilk, 2012).

The step-up is also easily scalable: you can increase the height of the step or add resistance with dumbbells or a barbell to match your fitness level. This versatility makes step-ups ideal for strength-building and injury prevention.

8. Glute-Ham Raise

The glute-ham raise is a lesser-known but incredibly effective exercise for targeting the hamstrings, glutes, and lower back. It’s a challenging movement that requires the use of specialised equipment, but it offers unmatched strength development for the posterior chain. A study in the Journal of Electromyography and Kinesiology found that the glute-ham raise elicits greater hamstring activation than more common exercises like the leg curl, making it a superior option for building strength (Ebben et al., 2009).

This exercise focuses on both the concentric and eccentric phases of the lift, which builds muscle and improves flexibility simultaneously. By strengthening the posterior chain, glute-ham raises can also improve performance in other compound lifts, such as deadlifts and squats.

9. Leg Press

The leg press is a compound movement that primarily targets the quadriceps, but also works the hamstrings and glutes depending on foot placement. It’s an excellent alternative to squats for individuals who may have limitations in flexibility or mobility. According to research in the Journal of Strength and Conditioning Research, the leg press allows for a greater range of motion in the knee and hip joints compared to squats, which can be beneficial for developing muscle mass in the legs (Signorile et al., 1995).

Leg press machines allow for precise control of resistance and movement patterns, making it easier to focus on hypertrophy without the need for stabilisation. This can be particularly helpful for bodybuilders or anyone looking to isolate their quads and build muscle mass without excessive stress on the lower back.

10. Calf Raise

Strong calves are crucial for overall leg development, yet they are often neglected in favour of larger muscle groups. The calf raise, whether performed with a barbell, dumbbells, or on a machine, directly targets the gastrocnemius and soleus muscles of the lower leg. A study in the Journal of Applied Physiology found that the calf raise is one of the most effective exercises for increasing calf muscle size and strength (MacDougall et al., 1977).

Calf raises are simple but essential for improving ankle stability and power, which translates to better performance in exercises like squats, deadlifts, and athletic activities that require explosive lower body movement. Additionally, strengthening the calves can help reduce the risk of Achilles tendon injuries.

Conclusion

Developing jacked and super strong legs requires a combination of heavy compound lifts, unilateral movements, and targeted isolation exercises. By incorporating these 10 exercises into your routine, you’ll work all the major muscles of the lower body and develop balanced strength and hypertrophy.
