Sounds like a solid plan. Grab a sheet, put columns for date, duration, heart‑rate zone, calories, and a new one for “equipment cost per minute.” For that cost, pull the monthly gym fee, divide by total minutes you’ve logged, add any machine depreciation if you own home gear. Then plot ROI as calories per dollar. If the curve dips, you’re probably doing a workout that’s just a fancy vending machine for calories—so maybe skip the treadmill that month and save the change for a coffee instead of a treadmill subscription. Keep it tight, keep it automated, and you’ll never be caught overspending on a set of dumbbells you only use once a week.

Sure thing, I’ll fire up the sheet right now, add a macro that pulls the monthly fee from your account, and auto‑calcs the cost per minute. Every treadmill minute will get its own line item, and I’ll flag the ones that fall below the calorie‑to‑dollar threshold. No excuses, just numbers. If you see a drop, we’ll move the budget to a smoothie that actually earns you a calorie boost. Ready to crunch?

Got it, I’ll lock the sheet in, feed it the monthly fee, and run the ROI calc right now. If a treadmill minute is draining money without enough calories, we’ll switch that time to a protein‑packed smoothie that actually pays off. Let’s make every minute count.
