Risk and reward always go hand in hand.
This is especially true in the process of natural evolution.
The Physical Enhancement Superpower only boosts one's physique by 10% in the Early Stage, offering a very low return. Therefore, its Awakening process involves almost no risk.
This Superpower originates from the stimulation of adrenaline within the body. Aside from a period of weakness after use, it has no other drawbacks. It isn't like exhausting one's Spiritual Power, which leaves a person mentally drained and utterly exhausted, requiring at least a long, deep sleep to recover.
That's why this Superpower is the one most Awakeners end up with. While it's weak in the early stages, it allows them to safely pass the trial of the Awakening phase.
At the same time, at Tier One Late Stage, it grants a 30% boost to physique. With a base physique of 150 points, this provides a considerable and rapid increase.
Compared to other, stranger abilities, it wasn't weak at all.
