2. You copy the hardcore gym members It's easy to think that to get as ripped as the guy in your gym who wows all the female instructions with one-armed press-ups, you have simply to follow his lead. The problem is that without knowing what someone else's fitness aims are, copying them could land you with unexpected results or an injury. Be careful who you take advice from, because some fitness instructions are not highly qualified and won't necessarily know what is best for you. 3. You go every day You may be someone who can't do anything by halves, but working out every day is not sustainable- either physically or mentally. If you go every day you won't be able to maintain a useful intensity and you'll get bored, and it becomes a chore and you'll start missing sessions and losing motivation. The suggestion is to incorporate proper rest days into your schedule.
