Hey everyone today im making my first guy on what is the best gym split and why.
First, how hypertrophy works in periods
the mechanism of hypertrophy works in periods of 48h. You will get a period of 48h of hypertrophy on a muscle after training it. After that, you start a period of atrophy. MAINTENANCE PERIODS DON’T EXIST.
So each muscle should be trained at least every 48h to minimize atrophy.
Next we have to understand how diminishing returns work
Diminishing returns are simple to understand : the more sets you do on a muscle per session, the less stimulating the next set will be and the more fatiguing the next set will be
Example : 1 set 2 times a week=5 sets 1x a week in terms of stimulus. The 5 sets will be more than 2.5x more fatiguing than the 1 set 2x (fatigue is not linear)
Conclusion : we want to maximize frequency to get as many 1st sets per sessions per week
Now that we understand that here will be my criterias :
-Frequency
-1st sets a week
-minimizing atrophy
-maximizing rest days
In conclusion the winner is : fullbody every 48h (every other day)
