Position the bench, not just its storage footprint
The Nighthawk is 27 lb lighter and 0.8 inches lower. Its shorter length can help maneuvering, but does not prove a particular rack or cable exercise fits. REP says its rear foot is designed to sit deeper in the Ares 2.0 working area; check the actual rack depth and your position. AB-5200 upright storage is listed at 3.1 square feet, but floor area alone does not describe the height or clear access needed to stand it up.
Keep the handle and wheels accessible and follow the upright-storage procedure on a level surface. Do not wedge a bench under a shelf or assume the flat height is its upright height. Neither the storage label nor the listed footprint confirms the stability of your room layout.

Measure a straight floor zone before testing the actual incline and unracking positions.
Long torso, decline and heavy loading: separate decisions
Long torso: a longer pad can provide more support, but height alone does not tell you where your head and shoulders land. Mark 36 and 41.7 inches on a bench or floor mockup and compare your actual setup. Decline: Nighthawk’s negative seat position is not a decline back pad. AB-5200’s optional adjustable rear post is required for its listed negative back angles. Confirm the configuration and any support requirements before buying.
Loading: compare bodyweight plus external weight with the manufacturer’s rating and permitted use. A larger rating does not prove better comfort or justify replacing a bench that already supports your training. These are published ratings, not our test results.
Compare the complete delivered price
Check the current Nighthawk price against an AB-5200 quote with the pad width and rear post you intend to buy. A component or starting price is not a complete decline configuration. Budget for delivery and verify return costs before buying a large bench solely for pad feel.
For a space-first incline setup, Nighthawk is the first comparison. For longer-pad support or intentional decline work, AB-5200 2.0 deserves the configured quote. If flat pressing covers your sessions, use the FB-5000 specifications and keep the budget for weights or flooring.
Connect this choice to your garage layout and your dumbbell loading needs.
