NASM-CPT, CSCS certified trainers. Every guide is built from peer-reviewed research and real coaching experience.
The JM press—named after powerlifter JM Blakley—is a hybrid between close-grip bench press and skull crushers. The bar lowers toward your throat/chin area rather than your chest or forehead, combining elbow extension with pressing. This advanced movement builds serious tricep strength for lockout power.
When to use it
Use as an advanced tricep strength exercise.
Who it's for
Advanced lifters and powerlifters.
Lower the bar toward your throat or chin area with elbows tucked forward—not flared outward like bench press and not pointed at the ceiling like skull crushers. The movement is a combination of lowering and pressing. Start very light to master the unusual movement pattern.

Combines benefits of two exercises.
Start light to learn movement.
When to Use the JM Press
Use JM press as an advanced tricep strength builder, particularly for powerlifters wanting lockout strength. Program it as a primary tricep exercise with moderate reps (6-10) and adequate rest. Master form with light weight before loading heavy.
What are common JM Press mistakes to avoid?
Lowering too far toward face.
During any pressing movement like the JM Press, this mistake reduces how effectively your Triceps can produce force. Focus on the muscle you're trying to work — if you can't feel your Triceps driving the movement, something is off.
Flaring elbows for optimal results.
Letting your elbows drift wide during the JM Press shifts load onto your shoulder joint instead of your Triceps. Keep them tucked at about 45 degrees to protect your rotator cuff and keep tension where it belongs.
Using too much weight initially.
Loading more weight than you can control on the JM Press forces compensatory movement patterns that bypass your Triceps. Drop the weight until you can perform every rep with clean form — your results will actually improve.

How to Program the JM Press
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3-4 sets of 6-8 reps. Rest 90-120 seconds.
