How to Build a Strong Core & Abs
In a Nutshell
Core strength training must distinguish **abs** (rectus abdominis, obliques, TVA for aesthetics) from broader **core** (including pelvic floor, diaphragm, glutes, back for stability and performance), prioritizing **contraction intensity** over high reps via progressive overload like other muscles (2-4x/week, 10-20 sets/muscle, load > endurance). Use **Three I's framework**: Investigate (e.g., Sahrmann test, Biering-Sørensen hold >200s), Interpret (tailor to look/feel/perform goals: 50/50 big lifts/isolation for aesthetics; 75% isolation for back pain), Intervene with anti-movements (Pallof press, planks), flexion (crunches), rotation, and compounds (deadlifts, carries). **5-step progression**: isometric control → anti-movement/eccentric fatigue → loaded anti → concentric fatigue → heavy concentric; big dynamic exercises maximize force safely, debunking daily high-rep myths.

Andy Galpin, executive director of the Human Performance Center at Parker University, discusses developing a strong core and great-looking abs. Warm-up questions: sit-up vs. deadlift for core/abs—which is better? Machine vs. free weight exercise—do free weights activate core more? How often to train core—every day since small muscles recover quickly?
Many common training approaches for abs and core do not align with current scientific evidence. Everyone wants a strong core and great-looking abs, but fewer achieve visible abs than have a million dollars in the bank. Solution: understand difference between core and abs, and specific outcomes desired.
Episode covers: what is the core, how abs work, training based on goals. Spoiler: not everyone means the same by strong core/great abs. Variables: exercises, order, frequency, load, rep range.

People do endless sit-ups, crunches, planks without results. Origins in 1960s-70s: Joe Weider, Arnold Schwarzenegger promoted high reps/sets, many days/week (as in Arnold's Encyclopedia of Bodybuilding). Not all bodybuilders followed, but Arnold's influence carried to mainstream.
