Looking to build strong legs, improve endurance, and achieve a balanced lower body? This workout incorporates four essential machine-based exercises to target key muscle groups including your quads, hamstrings, and calves. Ideal for all fitness levels, it focuses on progressive overload to maximize your results. Let’s break down each exercise: 

"Sled 45° Leg Press" is the foundation of this workout. It engages your quads, hamstrings, glutes, and calves for a powerful lower body push. Perform 4 sets with reps decreasing from 15 to 10 as the weight increases. Ensure a controlled tempo and full range of motion for optimal muscle activation.

"Lever Lying Leg Curl" focuses on isolating your hamstrings, enhancing strength, and improving knee stability. Complete 4 sets with the same descending rep structure (15, 12, 10, and 10 reps). Keep your hips stable and avoid lifting them to maximize tension in the hamstrings.

Next is the "Lever Leg Extension," essential for targeting your quads. With 4 sets of the descending rep scheme, focus on controlling both the stretching and contraction phases. Adjust the machine to ensure your knees align with the pivot point for safety and effectiveness.

Finish with the "Lever Seated Calf Press," which isolates your calves for improved ankle strength and lower leg mobility. The same 4-set sequence applies. Drop your heels fully for a complete stretch and drive upwards for a solid contraction at the top.

Consistency with this machine-based workout will help you build strong legs while minimizing injury risks. Always prioritize proper form, and adjust weights according to your strength levels to maintain progression.
