When you don't have too much time in the gym
Yesterday I didn't have too much time in the gym but if you're effective 45 min can be more than enough. When I do my training I usually put together small circuits with different excersises to save time and to make it more fun (not with heavy excersises). Sometimes I decide how many reps I do on each excersise and sometimes I work after time.
