The ultimate goal is maintaining a healthy lifestyle, which is more than your gym time each week.
Walk more places, play more games, chase your kids/grandkids around and use the fitness you’ve built.
Don’t major in the minors..
Strength training is based around big movements, squats, deadlifts, chin ups, dips etc
A diet of mostly unprocessed foods will do more for your results than a supplement stack
Find a way to make each week that little bit harder than the last. Track some things to measure your progress.
Feeling stuck is no good for training longevity either.
