- If you hit the gym to improve your physique, you’re probably striving for that ultra-hard, 3D look. The type of physique where every muscle pops and is perfectly shaped and sculpted. Unfortunately, many hit the gym without any real purpose and think that by simply going through the motions, they’ll see drastic changes in how they look. The sad reality is… that never happens. You need to change your workout to put yourself in a position to achieve the results you desire and look 3D.
