How effective are these biceps and triceps exercises?

The Effectiveness of Overhead Triceps Extensions and Pushdowns

This section discusses a study that shows overhead triceps extensions stimulate more muscle growth than pushdowns. It also mentions the effectiveness of chin-ups and wide-grip pull-downs for biceps.

Overhead Triceps Extensions vs. Pushdowns

• A study reveals that overhead triceps extensions stimulate significantly more muscle growth than pushdowns.

• This research validates the principle that overhead triceps extensions are effective for muscle development.

Chin-Ups and Wide-Grip Pull-Downs for Biceps

• According to a study, chin-ups and wide-grip pull-downs are as effective as barbell or dumbbell curls for bicep development.

• In contrast, another study found that dumbbell rows are considerably less effective than bicep curls.

Horizontal Force Production in Barbells vs. Dumbbells

This section explains how horizontal force production plays a role in the effectiveness of exercises using barbells or fixed implements compared to dumbbells.

Horizontal Force Production with Fixed Implements

• Exercises using barbells or fixed implements can be more effective due to horizontal force production.

• With a wide grip pulldown, pulling the bar inwards exerts force on the biceps, making it more effective.

• Similarly, pressing outward on a bench press with a fixed bar can activate the triceps effectively.

Limitations of Dumbbell Rows

• Dumbbell rows are less effective for bicep development because they lack horizontal force production.

• Moving the dumbbell out to the side does not provide direct demands for elbow flexion or activation of the biceps.

Effectiveness of Different Exercises for Biceps

This section discusses the effectiveness of various exercises for bicep development and suggests considering exercise intensity thresholds.

Exercise Effectiveness for Biceps

• Chin-ups are considered highly effective for bicep development.

• Rows and similar exercises are around 50% as effective as bicep curls.

• High rows or face pulls may be around 25% effective due to their activation of the biceps.

Exercise Intensity Thresholds

• If an exercise falls below a certain threshold, such as 40% of maximum voluntary isometric contraction (MVIC), it may not stimulate significant muscle growth.

• For simplicity, exercises below this threshold can be rounded up to zero in terms of effectiveness.

Considerations for Triceps Training

This section addresses considerations for triceps training, including the effectiveness of overhead triceps extensions compared to pushdowns and the complexity of assessing exercise effectiveness.

Overhead Triceps Extensions vs. Pushdowns

• Overhead triceps extensions are more effective than pushdowns but both train the triceps well.

• Factors like muscle length should also be considered when evaluating exercise effectiveness.

Complexity in Assessing Exercise Effectiveness

• Exercises like preacher curls or Bayesian curls may be more effective than dumbbell curls, but assigning specific percentages to their effectiveness can be complicated.

• Simplifying by counting exercises as fully or half-effective is often practical in program design.
