I workout and i don't have difficulties in anything except pushups. Everytime i try to do pushups i can't lift myself up i know that my arms are a little weak but how can i improve them?
Try a regression of the push up to gain strength and better form. Try seal push ups, then progress to wall push ups, then finally standard push ups. It is crucial you take your time with the progression, don't rush. Better to do it right than wrong. Good luck.
