Key Differences

EZ Bar Lying Close Grip Triceps Extension Behind Head is an isolation exercise, while EZ Barbell JM Bench Press is a compound movement.
Difficulty levels differ: EZ Bar Lying Close Grip Triceps Extension Behind Head is intermediate, while EZ Barbell JM Bench Press is advanced.
Both exercises target the Triceps using Ez-barbell. The catalogue does not establish which exercise is better for an individual goal.

Muscle comparison

Shared target muscles

Both exercises primarily drive elbow extension via the triceps brachii. The lying close-grip extension isolates elbow extension with the shoulder in a more flexed/overhead position, increasing long-head length and stretch under load. The JM bench press is a compound press that shares load between the triceps (especially medial and lateral heads at lockout) and the pectoralis major, so the triceps act as strong synergists rather than the sole drivers.

Secondary muscle differences

Secondary recruitment shifts: the lying behind-head extension lightly recruits anterior deltoids to stabilize the shoulder and resists shoulder extension, while chest involvement is minimal. The JM bench press recruits the chest and front delts heavily due to a more horizontal force vector and bar path; scapular stability and pressing mechanics matter more on the JM press.

Muscle involvement analysis

Activation differs by joint angle and force vector. The lying extension places the long head on a greater stretch (arm behind head, roughly 100–120° of shoulder flexion relative to torso), increasing length-tension stimulus during the eccentric. The JM bench uses a horizontal pushing vector so triceps activation ramps up in the mid-to-late concentric (near lockout). Expect higher triceps isolation EMG during the lying extension and a phased activation on the JM press where chest contributes early and triceps take over last 20–30% of the lift.

Equipment and setup

EZ Bar Lying Close Grip Triceps Extension Behind Head: setup

Ez Bar Lying Close Grip Triceps Extension Behind Head requires an EZ-bar, an adjustable bench (flat or slight decline), and space to position the bar safely behind your head. A spotter isn't mandatory but recommended when loading heavy.

EZ Barbell JM Bench Press: setup

Ez Barbell Jm Bench Press requires an EZ-bar, flat bench, and ideally a spotter or safety pins since it's a heavier, compound move. Good wrist/forearm and shoulder stability are necessary to keep the bar path tight.

Access and practicality

Exercise A (Ez Bar Lying Close Grip Triceps Extension Behind Head) — it’s more accessible for intermediate lifters because it uses lighter loads, is easier to set up without a spotter, and can be scaled with tempo and rep ranges. The JM press demands higher baseline pressing strength and safer load-handling equipment.

Learning and progression

Learning the movements

The lying close-grip extension has a shorter learning curve: focus on controlled eccentric and stable shoulders. The JM bench press is harder to master because it blends a narrowed press with a skull-crusher range and requires precise bar path and timing.

Progression considerations

The JM bench press offers greater absolute progression potential for strength because you can overload with heavier weights and it transfers to lockout strength in pressing. The lying extension offers linear progression via volume, tempo, and intensity techniques (drop sets, partials) but less maximal-load potential.

Limitations and precautions

JM Bench Press has higher injury risk — load and bar path can stress wrists, elbows, and anterior shoulder if technique fails. Lying extensions risk overstretching the long head when using excessive load or poor control, but controlled reps and conservative loading reduce risk.

Pros & Cons

EZ Bar Lying Close Grip Triceps Extension Behind Head

+ Pros

High triceps isolation—strong long-head stretch for hypertrophy
Easier to control tempo and time-under-tension (8–15 rep sweet spot)
Lower absolute loads reduce need for a spotter
Simple setup; good as an accessory after heavy pressing

− Cons

Limited absolute loading—less carryover to maximal pressing strength
Requires shoulder stability; can overstretch long head if overloaded
Less total-body stimulus compared with compound presses

EZ Barbell JM Bench Press

+ Pros

Superior for building pressing strength and heavy load progression (3–6, 4–8 reps)
Transfers well to bench press lockout and heavier compound work
Engages chest and shoulders for a compound stimulus
Efficient for strength-focused sessions—higher systemic load

− Cons

Technically demanding—requires tight bar path and shoulder control
Greater injury risk at heavy loads for wrists/elbows
Less pure triceps isolation; chest can dominate if form drifts

When Each Exercise Wins

For muscle hypertrophy: Ez Bar Lying Close Grip Triceps Extension Behind Head

The behind-head position increases long-head stretch and time-under-tension, making 8–15 reps with controlled eccentrics ideal for hypertrophy. Isolation lets you target the triceps without the chest stealing load.

For strength gains: Ez Barbell Jm Bench Press

JM bench lets you overload the triceps in a compound movement and improve lockout strength with heavy sets (3–6 reps). It also transfers to bench press and other pushing lifts due to higher absolute loads.

For beginners: Ez Bar Lying Close Grip Triceps Extension Behind Head

It’s easier to learn controlled elbow extension patterns and scale load safely. Beginners can build triceps size and tendon resilience before progressing to the technical JM bench press.

For home workouts: Ez Bar Lying Close Grip Triceps Extension Behind Head

You can perform it with lighter plates and a simple bench; it doesn’t require a spotter or heavy rack setup. The exercise is easier to manage in limited-space setups.

Frequently Asked Questions

Can I do both Ez Bar Lying Close Grip Triceps Extension Behind Head and Ez Barbell Jm Bench Press in the same workout?

Yes. Use the JM bench early as a heavy compound if you’re training strength, then follow with lying extensions as an accessory for 3–4 sets of 8–12 to maximize hypertrophy and finish the triceps. Adjust load so the second exercise isn’t performed to absolute failure.

Which exercise is better for beginners?

The lying close-grip extension is better for beginners because it’s simpler to cue (elbow tuck, slow eccentric) and uses lighter loads while teaching elbow-extension mechanics. The JM press demands more pressing strength and technical control before heavy loading.

How do the muscle activation patterns differ?

The lying extension produces more isolated triceps activation, especially the long head due to the overhead/behind-head shoulder position and increased length-tension. The JM bench shifts activation: chest and front delts work early, with triceps taking on more load near lockout when the elbow approaches full extension.

Can Ez Barbell Jm Bench Press replace Ez Bar Lying Close Grip Triceps Extension Behind Head?

Not fully. The JM bench builds strength and can stimulate triceps hypertrophy under heavy loads, but it won’t match the long-head stretch and isolated time-under-tension of the lying extension. Use the JM press for strength phases and the lying extension as targeted accessory work.

Comparison Summary

Use the Ez Bar Lying Close Grip Triceps Extension Behind Head when your goal is targeted triceps hypertrophy, controlled time-under-tension, or when you lack heavy-rack equipment. Aim for 8–15 reps with slow eccentrics and 1–2 second pauses at the bottom to maximize long-head stimulus. Choose the Ez Barbell JM Bench Press when you want to develop pressing strength and overload the triceps under heavier global load—program 3–6 heavy sets for strength or 4–8 for mixed strength/hypertrophy. Both have a place: prioritize isolation during accessory days and the JM press during strength phases.
