The heavy-duty ruck for your hybrid workout powered by a
$5 cinder block.

A rucking backpack built around a cinder block.

CINDERUCK carries an 8 x 16 inch base cinder block for weighted walks and hybrid strength workouts without specialty weight plates.

Load your block

Ruck your route

Mix in strength work

Use a cinder block with an 8 × 16 inch base, and secure it with the CINDERUCK straps. Your block supplies the weight; no specialty weight plates required.

Rucking is walking with added weight. Take your CINDERUCK along your usual walking route or make it part of a group workout.

Drop the pack to transition straight into squats, overhead presses, ground-to-overheads, and carries during or after your ruck.

Padded Grip & Rip Handles

Workout Generator

The included set of four padded handles attaches to the existing CINDERUCK straps, giving you a grip on each side for strength exercises.

Access the free Workout Generator for structured rucking and strength routines designed around your block.
