What the abs does
The rectus abdominis runs down the front of the trunk. It curls the trunk forward and, more often in training, stops the spine arching under a load.

Balance it
These undo what this muscle does. Training both is what holds a joint where it belongs.
- Trunk. The other side: Lower back.
Completes the loop. Training the abs without Obliques leaves a function out: it does a third job rather than the opposite one.
Track it in StatBlockFit
The app's training map draws this same body and fills each muscle with the sets you gave it this week, so the gaps are visible at a glance. Tap the abs there and it offers these movements, ready to add to a routine or log in one tap. The training guide explains the map, the routines and the overload rules.
For a session today, the Daily Bounty Board draws a full-body workout from this catalog for the equipment you have, and the Guild Ranker tells you what rank your bench press, squat and deadlift have earned.
Questions
What exercises train the abs?
Movements that train the abs as their main target include Ab Wheel Rollout, Front-Rack Carry, Medicine Ball Slam, Mountain Climber and Plank. The catalog in StatBlockFit lists 19 of them, and 28 more that train it on the way.
What balances the abs?
In the trunk pattern, the other side is lower back. Training both sides is what holds a joint where it belongs.
How do I progress abs exercises?
Add load in the smallest step the equipment allows once every set reaches the top of its rep range with good form, and move up a rung (from bodyweight to dumbbells, from dumbbells to the barbell) when the lighter version stops being a challenge. StatBlockFit does the arithmetic: it suggests the next weight after each session and lightens the load after two missed sessions in a row.
