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.
What's better for strength training â one set or multiple sets? Answers from Edward R. Laskowski, M.D. For most people, a single set of 12 repetitions with the proper weight can build strength and improve fitness as effectively as can multiple sets of the same exercise. The one-set approach also has the advantage of saving time, which makes it easier to fit into an exercise routine.
