Lindsay Lohan was spotted at an L.A. gym yesterday -- where she monitored her heart rate ... and alcohol intake.

After days of keeping her SCRAM bracelet hidden under a collection of boots, Lindsay once again modeled it off during a workout on the treadmill.

She can drop the pounds ... but not her ankle accessory.
