Prior EMG research indicates that the highest LD MVIC levels are obtained during maximal isometric shoulder extension. Aim: To address this gap by examining the level of LD activation during dynamic shoulder extension relative to the reference activity determined by maximal isometric shoulder extension.

This peer-reviewed study examines muscle activation patterns during common latissimus dorsi exercises including seated rows and lat pulldowns, investigating the influence of forearm supination, angle of pull, and scapula retraction on latissimus dorsi activation levels.

Using a pronated wide grip while pulling anterior to the head resulted in the greatest myoelectric activity of the latissimus dorsi when compared to other pulldown variations. Variations in latissimus dorsi exercises are capable of producing small changes in the myoelectric activity of the primary movers.

Greatest activation of the latissimus dorsi was found with pull-ups and chin-ups. Nineteen males completed five repetitions of the following exercises: lat pull-downs, inverted rows, seated rows, bent-over rows, TRX rows, I-Y-T raises, pull-ups, and chin-ups.

Lat prayers are a straight-arm cable pull-over with body movement that allows you to achieve high muscle tension in the lats all the way from their fully shortened to their fully lengthened position. EMG research confirms that the lats can achieve their highest muscle activity during shoulder extension, which is exactly the lat prayer movement. In contrast, lat prayers perfectly match the exercise's resistance with the strength and leverage of the lats, whereas vertical pulls lose lat tension when the lats are stretched (when arms are fully overhead).

This research examined exercises inducing maximum voluntary isometric contraction for the latissimus dorsi using surface electromyography. Related studies on pullover exercises showed that the barbell pullover emphasized pectoralis major muscle action more than latissimus dorsi, with higher activation depending on external force lever arm. However, these studies measured acute activation, not hypertrophy outcomes.

Here’s the ranking of latissimus dorsi exercises (based on EMG % of maximal activation): Surface EMG lets you measure how much muscle activity occurs during a specific movement. While activation alone doesn’t guarantee hypertrophy, it’s a key factor within the mechanical tension required for muscle growth. Seated Row (Cable) – 90% Activation.

This study examined muscle activation patterns during pull-ups and alternative exercises. The research focused on acute electromyographic measurements to determine which exercises most effectively activate prime movers, but did not measure hypertrophy outcomes or long-term muscle growth.

Muscle hypertrophy is primarily driven by mechanical tension, metabolic stress, and muscle damage. Research in sports science indicates that exercises producing greater time under tension and range of motion (ROM) across the full strength curve of a muscle tend to produce superior hypertrophy outcomes. Lat pulldowns typically operate through a limited ROM where tension is lost at full stretch, whereas straight-arm movements like lat prayers maintain tension throughout a greater ROM.

Lat prayers are so effective; they allow for stretch-mediated hypertrophy. And this is possible due to the lats producing the most tension during a shoulder extension, which is what they're doing during a lat prayer. Lat pulldowns are a great exercise but don't allow for stretch-mediated hypertrophy. Stretch-mediated hypertrophy can occur when a muscle is forced to endure high muscle tension from a fully shortened to a fully lengthened position.

Lat Pushdowns: Good for isolating and developing the triceps and lower lats. Lat Pulldowns: Best for overall back strength and width. Engages multiple muscle groups so good for upper body strength and posture.

For lat pulldowns, I advise clients to aim for between eight and 12 reps for muscular hypertrophy. If your goal is muscular hypertrophy, then unless you can do three to five sets of 10 reps on pull-ups, stick with lat pulldowns. As a certified personal trainer (CPT), I wouldn’t say pull-ups are better than lat pulldowns—they’re just different. Both are compound movements and work the same muscle groups.

The lat prayer keeps the arms relatively straight, offering a unique stretch-contraction cycle that isolates the lats without help from the biceps. This makes it excellent for improving the mind-muscle connection and enhancing muscle definition. The lat prayer is often favored as a finisher after pull workouts, providing deep lat activation without the spinal compression of heavy rows or pulldowns.

After testing hundreds of lat variations over a decade of training clients and athletes, this cable-based movement gives you the stretch of a pullover and the contraction of a row — all in one exercise. It activates your lats better than rows or pulldowns. Recommended: 3–4 sets of 8–12 reps with focus on deep stretch and full contraction.

The prayer stretch is described as a great stretch for the lats that can be done before training to help get into better overhead range for things like pullups and shoulder presses. The video emphasizes that to stretch the lats specifically, one needs to maintain external rotation and keep elbows tucked, noting that proper positioning is important to ensure stretching the right muscles rather than compensating with other areas.

User reports: 'I get hella pump out of lat prayers.' Another user notes that dumbbell pullovers are more of a chest exercise, suggesting that lat prayers may provide superior lat-specific activation compared to alternative pullover variations.
