Pullups are a super challenging strength training exercise, but when done with regularity they can greatly improve your overall fitness and strengthen many different muscles.
The muscles worked in a pull up are-
Latissmus dorsi, trapezius, erector spinae, infraspunatus, deltoids, rhomboids, biceps and core. The CHINUP is done with the palms facing you, this works the biceps more.
Not only are these different muscles and muscle groups strengthened, but so are the muscles in your hands.
It’s incredibly important to have good grip strength for nearly everything we do- walk the dog, open jars, climb rocks, grip ski poles, golf or bike, and lift weights to name a few.
If you can’t do a pull up on your own, use a band to assist you.
1st video show’s the full foot to straight leg in a band. This will give you the most assistance.
2nd video show’s using just your knee in a band this is a little less assistance
3rd video is a full pullup, notice the hands are facing forward. Chin-ups are when the hands face you, this require’s more bicep, equaling less back strength gain.
