My 20-minute strength training plan is necessary for me to accomplish my running goals and extend my healthspan. I don’t like strength training, and that is not easy to admit, given I have been a Team Beachbody Coach for 19 years. As we do for so many things these days, though, I turned to AI and used ChatGPT to solve my problem.

Coach Rich’s 20-Minute Strength Training Plan

For Your Specific Situation
Since you’re:
- running regularly,
- training nearly every day,
- maintaining a healthy body weight,
- and focused on longevity,
I would emphasize:
- Legs
- Core
- Balance
- Upper-body pulling strength
- Mobility
Those are the qualities most associated with maintaining independence and athletic performance as we age.
