Soulja Boy needs to become Soulja Man for his fight against Chris Brown ... and he's asking the fitness world for help with his weight gaining. 

Soulja took to Instagram Sunday with his request -- asking for any trainers and "muscle fitness companies" to come forward with advice on how to up his poundage. 

Quick suggestion ... eat ... lift ... pray.
