They look well-built without setting foot in a gym.
Building muscle too easily makes mesos worry about getting all buffed up with little exercise.
What mesos should do to stay fit:
Stretching should be an integral part of their work out routine. Stretching will help in toning muscles, lengthening them to appear less bulky.
About 20 minutes of cardio exercise per day is good enough to keep a healthy heart. It is important for mesos to do full body workouts. Overworking in one area will easily result in uneven muscle tone.
