Continue doing what u doing and u will end where u end!
More people should focus on mobility, streching (shoulders, lower back, hamstring ass and foot ankels) Doing full range motion to keep their bodies healthy and fit! Strikt nice form.
Maybe less heavy lifting and more volyme. Works fine for me! But Im not that old yet 37...but my body feel better than ever. Smooth nice, no pain!
Ego heavy deadlift squats and shrugs will probably make your body worse!
Arms have no limits, u can kill them ass much u want. Latpulldowns aswell. Dumbelpress for chest and shoulders. Side latera raises. Chins. Legcurl. Legextension. Squeese the muscle, feel the muscle. And u can continue that shit for houers without getting pain.
Lots of set, lots of reps.
