Most bodybuilders can’t enjoy a vacation, if they can’t bring the weights with them too. I recommend you take a vacation as a way to give your body a rest, but if you are in the middle of getting some good results, you may not want to stifle that with a break. You have two choices, either a dumbell workout or a calisthenics (bodyweight) workout.

Dumbell workout:

The Dumbell workout I posted a while back, will help you with a full body workout routine just using dumbells, without the need of even a weight bench or power cage.

Calisthenics Workout:

The other option is to do a Calisthenics workout, which is just
using your own bodyweight. Your workout will consist of at least pushups, chair dips, situps and possibly sprints for the legs. You probably will have to increase the intensity of your sets to make up for the lack of resistance from using your own bodyweight. To increase the intensity of pushups and chair dips you can do one or more of the following: rest-pause sets, reduce rest time between sets, increase set volume, adjust leg position.
