Hi Andrew,
Thanks for writing in.
With 14weeks you have a lot of time and options for your ME work.
I don’t suggest 14weeks of continuous upper body ME workouts. You may try 2weeks of ME, then 2weeks Max, with a rest week between and after. After this, you could consider going into the ME block of training.
Concurrent upper and lower ME is very hard to manage from a fatigue perspective. Often, I suggest 3-4 workouts with both upper and lower ME in a workout in the 2weeks leading up to the objective; these are ‘simulation’ workouts and are tiring. Around them the load is otherwise relatively light. This is a good time to climb lot of 5c granite with a heavy pack and the intended footwear, as a specific workout idea.
Blocking off upper and lower ME in 1-2week chunks works well. While you’re doing upper ME, for example, you could do a short max lower workout, like half-dose of hill sprints. Same for the lower ME period.
Hope this helps!
