A couple of years ago, at the height of the notorious 'dad bod' craze, people started to realize that Drake was ripped. He had been training for over three years, but the world only noticed when his Instagram page suddenly started heating up. Of course, like most other things, Drake has turned into a trend, and his followers flocked to gyms around the world on a body transformation quest to get 'swoll' like Champagne Papi.

Now, this is not to say that everyone who takes the benefits of exercise seriously these days is doing it because of Drake, but it's clear that 'making gains' is back in style, and people are going from skinny to shredded faster than half of us can blink. If it's done right, building muscle mass can actually give a lot of health benefits - prolong your lifespan and improve cardiovascular and bone health - as well as increase your chances of people sliding in the DM. Faster isn't always better, though. Each person inherits different strengths and weaknesses from the gene pool, so it's important to take your time and found out what gym workout is best for your unique body. To dispel that last little thought in your head, no - steroids are never a good option unless you want to add the increased risk of heart disease and stroke to your exercise routine.

Here at Bored Panda, we decided to compile a list of people who bulked up big-time and barely look like the same people in their 'before' photos, from women fitness maniacs to guys who have managed to get ripped using no exercise equipment at all. We've also included the timespan of their progress, but keep in mind that everyone builds at a different pace!
