Anecdotally as someone who strength trained on a recreational basis the last 20 years (and run a marathon just to see if I could), nothing beats heavy lifting.
A Strong lifts 5x5 program build around squat, deadlifts, bench and shoulder press can always make me feel pumped for the day!
Same. Finding heavy lifting changed my life if I’m honest. The strength gains, body comp, and how I felt was amazing.
To maintain my health I supplement with iron. In a form of barbells and dumbbells.
Shoutout to Barbell medicine. It is a good youtube channel by 2 lifting MDs (formerly associated with Starting Strength).
