151: Four things

Resistance rods on a Bowflex exercise machine. From left to right the bars are rated at 10, 10, 30 and 50 pounds of resistance, you can hook them in any combination of up to five bars (the 5-pound bar isn't pictured).

If you see each bar as a binary, and hooked means 1, that's 31 (binary 11111) possible positions per side. You could get fancy and allow for asymmetric values, so the maximum would be 11111 11111, or 1023.
