How to Do the Decline Crunch
Intermediate core exercise — bodyweight.
The Decline Crunch is an intermediate-level core exercise that puts focused tension on the abs, using no equipment. As an isolation movement it lets you target the abs directly with less full-body fatigue, so it pairs well as an accessory after your main lifts. You can do it at home or while travelling — no gym required — which makes it easy to keep in your routine consistently.

- 4Pause for a moment at the top, then slowly lower your upper body back down to the starting position.
- 5Repeat for the desired number of repetitions.
How to program the Decline Crunch
- Use the Decline Crunch later in your workout as an accessory, after your main compound lifts.
- Warm up with one or two lighter sets before your working sets to prime the movement.
- As an isolation move, 3–4 sets of 10–15 reps works well, resting 45–75 seconds. Chase a strong contraction and controlled tempo over heavy weight.
- To progress, add reps, slow the lowering phase, or move to a harder variation once the current version feels easy.
