Artificially Enhanced Physiology: As a Super Soldier, Steve Rogers possesses peak human abilities, such as formidable intelligence, strength, speed, durability, agility, stamina, dexterity and reflexes, as well as a healing factor that prevents him from being drunk. The serum metabolized and enhanced all of Steve's body natural abilities to the peak of human potential, pushing into the early levels of superhuman potential. It transformed a frail and sickly Steve into the "perfect" specimen of human development and conditioning. Captain America frequently exhibits superhuman abilities as a result of the Super-Soldier serum. Captain America is extremely intelligent, strong, fast, agile, and durable. Although the SSS is definite, he maintains an overall healthy lifestyle including a regular exercise regimen and a balanced diet. This appears to have increased his capabilities further, much like how it increases strength in non-enhanced humans.
Enhanced Strength: Rogers' strength is enhanced to the peak of human potential, moving into the early levels of superhuman potential. His strength allows him to overpower normal humans, even humans who have Olympic-level strength and even alien ground troops and robot sentries. He can tear through objects such as reinforced glass, bend metal bars, slam through solid walls and pry open the steel doors of the Helicarrier. In combat, his strength allows for him to send enemies such as soldiers flying from mere punches and kicks. His strength is inferior to high-level super-humans like the Hulk or gods like Loki or Thor. Nonetheless, his combination of his strength, and combat skills him an incredibly formidable opponent to those that would try to attack him. During his USO tours, Steve was able to lift a motorcycle frame with three show girls sitting on top, without any strain. Once he boarded the Lemurian Star, Rogers was able to defeat the mercenaries with a combination of strength, speed and offensive use of his shield. Also, while in an elevator, Rogers was able to overpower a dozen skilled combatants. He was also able to pull himself away from the immense magnetic force applied on his hand by a magnetic lock, which most others cannot achieve. Steve Rogers was able to lift a massive metal support beam to save a trapped Winter Soldier. Rogers was able to support the concrete debris to save Black Widow and himself from being crushed. It is evident that the strike power of Captain America is greater than humans as men with all their equipment and aliens in armor flew back several meters in air after being attacked and are knocked out cold after only one hit. When chopping wood Rogers ripped apart a block of wood trunk in half using his bare hands. More recently, he has been able to throw a moving motorcycle at a jeep, and displayed the strength to toss Ultron through a concrete pillar, during their fight in Seoul. During Ultron's initial attack on Sokovia Cap was also able to support the weight of an entire car, proving his strength goes well beyond that of an ordinary man.
