Home Gym Setup for Cardio Only

No weights, just engine work. Pick one cardio piece and go deep.

Cardio-only goals (marathon training, weight loss, joint-friendly conditioning) reward depth over breadth. Pick the one piece that matches your joints and motivation, then add a heart-rate monitor.

Coach's note

Pick the cardio piece you'll actually use, not the one with the best specs. A daily 30-min walk on a walking pad beats a weekly 60-min run on a treadmill that intimidates you. Consistency > capacity.

Nice to have

Add these once the core kit is in place. None are essential.

Walking Pads

The original and still the best-reviewed. 4" thick fits under most standing desks, folds in half for storage, remote control. 2.25 CHP motor handles 4-hour days.

Foam Rollers & Mobility Tools

The benchmark hollow-core EVA roller. Multi-density surface mimics thumbs/fingertips/palms, hollow core makes it lighter, and the build outlasts decade-old usage reports. The default starting roller for a reason.
