Hi, I'm 50 yo and I've been following a 3x/week full-body starting strength type program for about 6 months. Everything's going good. I still have low numbers but I've been making steady progress.
I'd like to add grease-the-groove training for pushups and banded pullups to my program. By GTG I mean 4 sets a day, six days a week, at least an hour between sets, each set about 50% of my one set max reps.
Is this an OK idea? Will it obviously interfere with recovery from the weightlifting? The weightlifting is the basis of my program and I don't want to mess it up, but if the GTG exercises don't interfere with recovery, I'd like to add those too. So is there any clear conflict between the high-intensity low-frequency weightlifting and the low-intensity high-frequency calisthenics? Or will they co-exist peacefully because they're different regimens?
EDIT: I forgot to add that with the GTG program, you also add one rep to all the sets every day, until you cannot do a set with good form, then you retake the max reps test, and begin all over, with the option of adding another set. This is the gtg program from 100pushups.com.
