Difficulty level: Beginner
Target Muscle: Triceps
Equipment: Dumbbell
Instructions for proper form
1. Start by lying on a decline bench with your back flat against it. 2. Hold a dumbbell in each hand with a neutral grip (palms facing each other). 3. Extend your arms straight up above your chest, keeping your elbows locked. 4. Slowly lower the dumbbells towards your forehead by bending at the elbows while maintaining a supine position. 5. Stop when your forearms are parallel to the ground, then engage your triceps to lift the dumbbells back to the starting position. 6. Ensure your elbows stay close to your head throughout the movement to maximize triceps activation.
Common mistakes to avoid
1. Allowing elbows to flare out, which reduces triceps engagement. 2. Lowering dumbbells too quickly, risking injury; maintain control throughout the movement. 3. Lifting weights that are too heavy, compromising form. 4. Not fully extending arms at the top of the movement, limiting muscle activation.
Benefits
Specific benefits of the exercise
The Double Dumbbell Decline Bench Skull Crusher effectively targets the triceps, helping to increase strength and muscle mass in the upper arms. This also improves overall upper body pushing strength.
Expected results and timeframe
With consistent training and a proper diet, one can expect to see increased tricep strength and size in approximately 4-8 weeks. Additionally, improvements in pressing exercises may be noticed..
Who this exercise is best for
This exercise is ideal for beginners looking to build upper body strength, individuals focusing on bodybuilding, and those aiming to enhance tricep development for better performance in pressing motions.
Scientific studies supporting its effectiveness
Research indicates that skull crushers are one of the most effective exercises for isolating the triceps, supporting hypertrophy and strength gains in the upper body when performed consistently (Schoenfeld, 2010).
Variations
Beginner modifications
1. Use a lighter weight to start until you master the form. 2. Perform the exercise on a flat bench if decline is too challenging. 3. Consider performing one arm at a time to build confidence and strength.
Advanced progressions
1. Increase the weight of the dumbbells as strength improves. 2. Implement pauses at the bottom of the movement for added difficulty. 3. Try an incline bench to alter the angle of the exercise, targeting different parts of the triceps.
Integrations
Complementary exercises
Incorporate exercises such as push-ups, tricep dips, and overhead tricep extensions to create a well-rounded tricep workout.
Super set recommendations
Super set this exercise with close-grip bench presses or tricep pushdowns to maximize triceps fatigue and growth.
Sample workout routines
Example routine: 1. Double Dumbbell Decline Bench Skull Crusher – 3 sets of 10-12 reps. 2. Tricep Dips – 3 sets of 10-12 reps. 3. Overhead Tricep Extension – 3 sets of 10-12 reps.
Exercise combinations
Combine this exercise with chest press movements such as barbell bench press or dumbbell bench press for an effective upper body workout.
Best time to do this exercise in your workout
This exercise should ideally be performed towards the end of an upper body workout after compound movements like bench presses and rows, to focus on isolating the triceps.
