How To Get Six Pack Abs | Ab Training Science Explained ft. Christian Guzman

Summary by Krater

This video examines scientific literature on abdominal training to determine the effectiveness of various exercises for growing the rectus abdominis. It concludes that compound lifts like squats and deadlifts activate the abs relatively little, while specific movements like ab slides, hanging leg raises, and posterior pelvic tilt planks produce high muscle activation.

From the video

Answers: What are the best exercises to train your abs based on scientific evidence?

• abdominal muscle anatomy
• EMG activity of core exercises
• squats and deadlifts for ab development
• crunch and sit-up variations
• plank modifications for core activation
• rep ranges and training frequency for abs

Exercises

• crunch · bodyweight
• sit-up · bodyweight
• back squat · barbell
• deadlift · barbell
• overhead press · barbell
• ab slide · ab slide tool
• double leg thrust · bench
• side bridge · bodyweight
• hanging leg raise · pull-up bar
• plank · bodyweight
• long lever posterior pelvic tilt plank · bodyweight
• weighted crunch · weight plate
• partner assisted decline medicine ball crunch throw · decline bench and medicine ball
• half kneeling cable chop · cable machine and rope
• superman · bodyweight
• lower back extension · hyperextension bench

What it concludes

• Squats and deadlifts do not effectively activate the rectus abdominis or external obliques, showing less than 20% activation.
• Traditional front planks do not activate the core as effectively as modified versions like the long lever posterior pelvic tilt plank.
• Performing crunches as part of a total body resistance training routine has no negative effects on posture.
• Ab slides and double leg thrusts produce greater EMG activity for the rectus abdominis compared to traditional crunches and side bridges.
• Exercises that bring the pelvis towards the chest, such as hanging leg raises, target the lower region of the abs better.
• Standing on an unstable surface like a BOSU ball does not increase core muscle activation during compound lifts like squats and deadlifts.
