If you’ve ever wanted to learn a variety of new exercises for specific muscle groups, check out MuscleWiki. It’s free, easy to use, and even calculates your macronutrients and calories.
Created by w0ts0n (notanotherlifter on Reddit), MuscleWiki is a slick, beginner-friendly fitness resource with a clean interface. I really like the interactive map of the main muscle groups. For example, when you click on biceps, you are taken to a separate page with a list of the exercises that work that particular muscle, complete with descriptions and GIFs. It’s not very detailed yet nor does it have an extensive library, but it offers a good starting point for newcomers.
You can also calculate your calorie needs based on your fitness goal, you can then plug your results into the macronutrient calculator for a breakdown of your macronutrients. Another cool feature is the 1-rep calculator, which can estimate the maximum amount of weight you can safely lift for one rep without actually testing it yourself in the weight room (a risky maneuver).
Overall, MuscleWiki is still a work-in-progress. The creator told ProductHunt users that he is still working on expanding the exercise database with such additions as bodyweight exercises. Meanwhile, ExRx.net is a highly detailed website for fitness enthusiasts of all kinds to jump into.
