Thoughts on use of the sauna. Just recently started at 60 including sauna and it has been a game changer.

Hi Keith. What exercises would recommend for the lower back?

When you have a full time job and on the side are part of a startup then time for exercise is limited. When you on top of that deal with a son with extreme OCD daily life is not easy. I still manage to do workout lifting weights, but cardio is skipped. I wonder how other deal with balancing job, workout and cardio?

I wanted to get some opinions on the number of sets we're all doing. Because I work out during my lunch breaks, my time is limited to about 20-35 minutes. I focus on doing just 3 exercises per workout, 3 sets each, but I make sure to take every set to true failure. For me, this is highly effective. I notice a lot of guys here are doing 4 to 6 sets per exercise. Honestly, I'm trying to understand the benefit. Is 4-6 sets too many? If I tried to do 6 sets, I feel like I'd just be wasting time or holding back on my first few sets just so I could survive to the end. Are those extra sets actually building muscle, or is it just pumping too much blood without adding much value? Would love to know the reasoning behind the higher set counts!

I have put together, as mentioned before, a push pull legs workout that should take 1.5hrs to complete. I find myself always finishing after about 65 minutes. The only thing I can attribute this to is my rest between sets. I seem to take a quick breather and start the next set. Definitely not a 1-1.5 minute break in between. Does this hurt any thing? I do 4 sets any where between 12-16 reps but feel I am wasting time resting in between.
