These are just a couple examples. I like to stick to no more than four or five exercises; otherwise, you could find yourself standing in too many lines waiting to use equipment. Another reason I choose just a few exercises is because any more than four or five is overkill. You don’t want your body to be taxed to the point that your form becomes compromised. In terms of how many reps you do—pick a number, I don’t really care. Your level of effort is what really counts.
