REST TIP::- Take less rest between the sets and more rest between exercises – Time of rest totally depends upon the training or on your physical condition. If you are absolutely normal and doing general work out, then the rest time for you (between exercises) should be 2.5-3 minutes and between sets should be 1 minute. However, athletes with unlimited strength take even lesser rest. For hypertrophy and endurance, athletes optimal rest period is of 30-60 seconds
