Reactive Training Systems

Definitely possible. I am doing it in my current mesocycle.

The trick is finding/learning the correct amounts of stresses, intensities, planning, exercise selection, etc.

It isn't an easy thing to figure out at first. It took me a few mesocycles of reactive training to understand what I needed to do.

If you haven't already, you really need to read the RTS manual. It is fairly laid out on how to program training for you and you alone.

I have always taken this philosophy with my training and programming..."build your weaknesses...exploit your strengths."

If there are some heavy compound squat/bench/deadlift movements that you absolutely suck at...start there...build them up.

If there are some heavy compound squat/bench/deadlift movements that you are good at and respond well to, then utilize them to get better.

It sounds to me like you need to changes some variables.

Try a new template.
3x upper
3x lower
(over 3 days or 6 days)


4x upper
4x lower
(over 4 days)

I've even tried
4x lower
6x upper
(over 6 days)

Try longer/shorter mesocycles, new exercises, spend more time on conditioning, try an overload transition week, concentrated loading, independent stress management (by exercise slot) etc...the changes we can make with these variables are just scratching the surface with how RTS can be manipulated for your progress.

im sure it is but i cant seem to do it at age 45.
