There will never be a Melvin Goodrum Fitness center for these reasons:
Melvin is an out of shape obese slob in the off season & when he diets down to reach a normal bf%, his lack of muscle becomes evident & he looks like a normal skinny/fat out of shape guy. Both versions of Melvin look like the 'before' pictures of a supplement ad. Why would anyone pay to have him give them advices.
Melvin Goodrum lives pay check to paycheck & there is no way he can afford the rent & equipment for a studio.
Melvin Goodrum has no real legit degree for anything fitness related. All of his degrees are bogus diplomas bought online & carry no weight.
Melvin Goodrum has no follow through or drive to succeed. He just likes to boast about things to boost his low self esteem but all of his ventures fail due to his laziness & lack of cognitive prowess.
