Titans are peak human physically, further enhanced by the Light to superhuman levels, and even more by the field plate they wear, specifically by the micro-servos laced through-out the undersuit and armor combining multiplicatively. Titans are so strong, they regularly snap their triggers in the field without intending to, and one of the most well known Titans, Saint-14, caved in a Fallen Archon's skull with just his head and helmet. I'm not sure how well Exo feats of strength translate to a Human or Awoken, but I imagine they're rather similar in general because of the lack of ANY gameplay differences.
