Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. European and U.S. regulations allow small amounts to be used as a food additive.
Like others have said, it depends... If you're doing sets of 8-12 reps with moderate weights, rest 60-90 seconds. if you're doing high weight low rep (3-5 reps), then rest 2 minutes And if you're doing real heavy stuff like squats, deadlifts, I'd recommend at least 3 minutes.
Here now are the most commonly used rep ranges along with their primary training effect: 1  1-5 Reps Per Set = Mostly Strength. 2  5-8 Reps Per Set = Strength AND Muscle Equally. 3  8-10 Reps Per Set = Muscle With Some Strength. 4  10-12 Reps Per Set = Muscle With Some Endurance. 5  12-15 Reps Per Set = Endurance With Some Muscle.
