As of right now I have been doing F1 and H1 since January 6th. So far, so good! I was humbled on most of the exercises... I had no idea my back mobility+endurance was so terrible (think ABH). Anyway, to my question!
I have been doing squats and dead lifts after my F1 work. It has gone well, but soon enough I will not have access to the gym that I weight lift in (it's a college gym). I enjoy adding in some leg and grip strength to my F1 work, because those are important to me as a guy who does physical labor for work. I also like being good at hill sprints, because being good at hill sprints makes everything I do easier (hike, soccer, run around, frisbee, etc).
So my idea was to add in farmer's walks for grip/total body strength and some hill sprints to F1+H1. I believe farmers carry would be a good replacement for dead lifts, while hill sprints would be good for conditioning and working the same muscles as squats.
Thoughts? Too much work? I think it would work if I ate enough+only did the above exercise 1-3 times a week.
