Difficulty level: Intermediate
Target Muscle: Hamstrings
Equipment: Stability Ball
Instructions for proper form
1. Begin by lying on your back on a mat with your heels resting on a stability ball. 2. Lift one leg off the ball and keep it straight, while the other leg remains on the ball. 3. Slowly bend the knee of the leg that is on the ball, pulling the ball towards your glutes. 4. Make sure to keep your hips elevated and in line with your body throughout the movement to maintain stability. 5. Return the ball back to the starting position by extending your knee. 6. Repeat for the desired number of repetitions and then switch legs.
Common mistakes to avoid
1. Letting your hips sag during the movement. 2. Lifting the non-working leg off the ball or bending both knees at the same time. 3. Not engaging the core, which can lead to lower back strain. 4. Using momentum instead of controlled movements.

Variations
Beginner modifications
1. Perform the exercise with both feet on the ball to stabilize before trying single-leg curls. 2. Decrease the range of motion initially by not bringing the ball all the way to the glutes.
Advanced progressions
1. Add a stability challenge by lifting both arms off the ground. 2. Incorporate a resistance band around your ankles to increase tension on the hamstrings.
Integrations
Complementary exercises
1. Deadlifts for overall hamstring strength. 2. Glute bridges to engage hip extension. 3. Plank variations for core stability.
Super set recommendations
Superset with glute bridges or lunges for an advanced workout focusing on the lower body.
Sample workout routines
1. Warm-up: 5 min of light cardio. 2. 3 sets of 10 reps of Stability Ball Single Leg Hamstring Curl. 3. 3 sets of 12 reps of Squats. 4. 3 sets of 15 reps of Deadlifts. 5. Cool down with stretches focusing on hamstrings.
Exercise combinations
To balance workout routines, combine this exercise with quad-dominant movements like lunges or squats to ensure full leg development.
