A dumbbell tower eats about 30 sq ft of floor. One adjustable pair replaces 10-15 fixed pairs, for $120-400 instead of $800-1,200. The one type to skip: generic twist-lock sets under $80. The mechanism typically fails within 6-18 months.

We built a free calorie calculator for lifters. TDEE plus protein/carb/fat targets, updating as you type. Runs on Mifflin-St Jeor — the formula dietitians actually recommend — with Harris-Benedict included if you want to compare. No signup, no email wall. Link in the reply.

Most home gym regret starts with buying before measuring. We built a free 3D planner: pick your room size, drag in real equipment, get clearance warnings and a live floor-space readout. Runs in the browser. No signup.
