Not one of the coaches for the app but any of the programs will help but really putting on mass comes down to nutrition. I would pick whichever program best fits the muscle groups you’re trying to address. But again making sure that your diet is on point is the most important factor.
Appreciate that a lot🙏🏽 nutrition is on point 96% of the time, nutrition isnt a problem. But decided its time to run a new program to target the lacking parts that need work, thank you🙌🏽
