Did you ever switch to dc training? I've used it in the past with great results. I'm 50 so I've been doing higher reps with moderate weight.
I haven't done DC the way it's laid out,to a T in quite a while... considering it now as I am planning on bouncing back from being so sick...
Glad to see your back and training again. I work in healthcare also and everybody is sick.
I've ran dc training a couple of times and it's brutal, but had great gains. Dante knows his shit
