-
Ab training is not fundamentally different from training any other muscle group.
-
Common approaches like "100 crunches every morning" are ineffective for building muscle, similar to doing only bodyweight squats for leg hypertrophy.
-
Expecting significant results from only a few weeks of ab training is unrealistic.
-
Training your abs can make the muscles physically bigger.
-
This includes the obliques (side abdominal muscles).
-
Proper oblique training involves using one dumbbell for side bends, not one in each hand.
-
Making ab and oblique muscles bigger can make them pop out slightly more at any body fat level, but the effect is minimal.
-
Making the abdominal muscles bigger will also slightly increase waist size.
-
Ab training is beneficial if aiming for a muscular midsection ("burly bear" or "muscle daddy" look).
-
Ab training will NOT make your waist smaller. Bigger muscles cannot mechanically shrink an area.
-
Ab training will NOT make your abs visible at high body fat levels (e.g., 23%). Fat covers the muscles.
-
Ab training does NOT cause significant spot reduction of fat in the abdominal area.
-
Ab training does NOT burn a significant amount of calories compared to other activities like walking.
-
Ab training will NOT significantly change the amount of fat on your abs at a given body fat level.
-
Expecting a dramatic difference in appearance from ab training, especially within a short timeframe (weeks/months), is unrealistic. Noticeable changes require years of dedicated training and are still only mild to moderate.
-
To effectively train abs for size (hypertrophy), treat them like any other muscle group.
-
Use standard hypertrophy principles:
- Exercises with tension at the stretch (not just pump-focused).
- Good eccentric (lowering) control.
- 2-4 training sessions per week.
- 3-6 working sets per session.
- 5-30 repetitions per set. Avoid high-rep sets (like 100 crunches) for hypertrophy.
- Train close to failure (0-3 reps in reserve) on working sets.
- Use load or repetition progression to make training challenging over time.
- Utilize resistance (machines, weights) and progressively load movements.
-
Planks (isometric movements) are not effective for muscle growth as they lack concentric and eccentric phases.
-
Doing casual sets of crunches with many reps in reserve is ineffective for hypertrophy.
-
Achieving noticeable abdominal muscle growth takes years, not weeks or months.
-
Expecting drastic results (e.g., a shredded six-pack at high body fat) is unrealistic and leads to disappointment.
-
Visible abs are primarily achieved by lowering body fat, not solely through ab exercises.
-
Many people train abs incorrectly, not hard or properly enough (e.g., planks, too many reps away from failure).
-
People often train for too short a duration (weeks/months) for noticeable results.
-
People have unrealistic expectations about the results of ab training (smaller waist, spot reduction, shredded look at high body fat).
-
There is a large industry promoting ineffective methods (gadgets, belts, quick fixes) that claim to produce abs without significant fat loss. These are scams.
-
Train abs hard and properly for years if you want mild to moderate visible differences, but understand this also slightly increases waist size and results are only apparent at lower body fat levels.
-
If you are not willing to commit to years of consistent, challenging ab training for modest results that require low body fat to be seen, then dedicated ab training may not be worthwhile.
-
Visible abs are primarily a result of achieving a low body fat percentage through diet and overall training, not just ab exercises.
