There been some talk around in the last year or so about additional bodyweight in the form of muscle is more dangerous that the additional weight from fat due to the heart having to work harder to pump blood through the additional muscle mass.
I can see what they’re saying as far as carrying more weight around but my way of thinking is that if you gained 30 lbs of lean muscle over thirty years of hard training , wouldn’t the heart have become stronger and adapted to the additional weight due to the training ?
If the weight gain came too quickly from various drug cycles and forced feeding … like 60-80 lbs or more in a year or two I could understand that the heart not being able to keep up , but not something like gaining a pound or two a year over a long time.
Thoughts on this ?
