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.
UPGRADE. To build more muscle and finish your workout in less time, try cutting back on your rest periods by five to 10 seconds every week (don't increase the weight). For instance, if you rested 60 seconds between sets this week, rest only 50-55 seconds next week.n other words, the amount of time you rest between sets can have a major impact on how the exercise you're doing affects your body.. Rest too long and your workouts lose intensity; rest too little and you burn out too quickly. Luckily, we have expert advice on how to tailor your rest periods to any fitness goal.
