Yes, Peter Attia says this precise thing in his book 'Outlive' and also his podcasts. I stopped using the gripper after that.

I started lifting weights 1 year and 2 months back - whole body compound lifts i.e. deadlift, squats, bench press, overhead press - and results are phenomenal.

Before that had been doing body weight for a decade push ups/ pull ups/ planks, and for some reason thought it was sufficient for me. Only when I pivoted to these (lifting weights) after a chronic pain developed due to excessive running, did I feel the difference.

Overall lifting weights and counting protein intake seems to be life changing. The chronic pain also went away.
