Basic Lift (BL)
see Lifting ST (p. 65)
Basic Lift is the maximum weight you can lift over your head with one hand in one second. It is equal to (STxST)/5 lbs. If BL is 10 lbs. or more, round to the nearest whole number; e.g., 16.2 lbs. becomes 16 lbs. The average human has ST 10 and a BL of 20 lbs.
Doubling the time lets you lift 2xBL overhead in one hand. Quadrupling the time, and using two hands, you can lift 8xBL overhead.
The amount of equipment you can carry – armor, backpacks, weapons, etc. – is derived from BL. For more on this, as well as a ST-to-BL table, see Encumbrance and Move (p. 17).
