Which exercise is suitable for improving vertical jump?

The kettlebell jump squat is particularly effective for improving vertical jump because it incorporates both strength and explosive power. This exercise combines the use of a kettlebell and the jumping motion, which engages the leg muscles, particularly the quadriceps, hamstrings, and calves. By performing a jump squat, you train your body to produce high force quickly, which is essential for vertical jumping. The kettlebell adds resistance, further increasing the intensity of the workout and stimulating muscle growth and power development.

In contrast, other exercises listed may focus on different muscle groups or movements that do not directly contribute to vertical jump performance. Squat thrusts involve a full-body movement, primarily aimed at conditioning rather than explosive power generation. Leg extensions target the quadriceps in a more isolated manner, which does not translate as effectively to the vertical jump. Seated calf raises focus specifically on the calf muscles and also lack the explosive component necessary for improving vertical leap ability.
