Arms and Abs Need to Be Trained? Double Bars Will Satisfy You
So convenient! Just using parallel bars can satisfy your requirements for thicker arms and strong abs!
Next, I'll share two exercises that can make your arms stronger and also build more defined abs!

To make your arms stronger, the main muscle groups are the biceps and triceps. One is responsible for pulling and the other for pushing, which can both be achieved on parallel bars. To build strong abs, simply lifting your legs is enough.

First exercise is the leg raise assisted pull-up. Since the parallel bars are thick, they are more effective for building the forearm muscle groups. Train assisted pull-ups while lifting your legs, which will provide more stimulation for your abs and biceps. You can start with bent-leg exercises and then transition to straight-leg exercises.

The second exercise is parallel bar arm extension, which is a classic pushing exercise. In addition to stimulating the triceps and biceps in your arms, it also helps improve the strength of your chest and shoulder deltoid muscles.
If you feel the abdominal training intensity is not enough, you can specifically practice supporting leg raises or L-shaped exercises.
Keep training these three exercises, gradually increasing the intensity, and combining rest and exercise. You will gain strong arms and strong core strength.
