9 Best Cardio Exercises for Small Spaces (No Equipment Needed)

8. Pike-Ups

Pike-ups are a compact, core-heavy option that fits tight quarters and keeps feet in one spot. Start in a plank or a downward-dog-like position; drive the hips up toward the ceiling while keeping hands planted, then return to plank. This movement taxes the shoulders and abs while giving a cardio-like burn when performed in quick rounds. If you need lower headroom or less demand on the shoulders, perform pike-ups with hands on an elevated surface like a sturdy bench or low table. Beginners can do slow pike pulls or alternate with shoulder taps to build core strength. Watch for a sagging lower back or rushed reps, which reduce core engagement and can strain the lumbar area. Pike-ups are especially helpful for people who want a different stimulus than leg-focused cardio; they pair well with lunges or squats in a compact circuit.
