I have been lifting weights since I was 17, I'm 26 now. Time flies. Anyway, I spend about 1-2 hours a day, 6-7 days a week. Yes, even Sundays regardless if it bothers you Sunday churchgoers. I love it, enjoy it and feel great when I work out. Its healthy for the body and for the mind. Scientifically it is known to relieve stress and guess what? You don't need science to prove it. Run, jog, walk, lift weights, cardio, etc. You do it, you witness for your self the good physical, mental feeling and relieving of unhealthy stress.
As long as you don't do it to idolize yourself (prideful sense), you are fine. In regards to spending more time lifting weights than reading the bible, well how many people read the bible for 1-2 hours a day? I read a few chapters a night, occasionally more or less. Does this make GOD angry? I cannot imagine. The first thing you need to make sure is that you do not put anything ahead of GOD. Time spent on something is not proof / evidence that you put something ahead of GOD. That's an unrealistic expection. Examples? Typical 8 hour work day, family time, personal time for yourself. Exercising is very healthy and GOD's gift. Like I said (and many will say too, those who exercise daily), it is a way to gain physical and mental health benefits. Those two together make you feel better and that can uplift your spirit. Put you in a better mood, better relationship, better attitude.
There is a Christian health book called "Makers Diet". Read it. Blessing from GOD.
Remember, as long as you don't put something above GOD, your ok. As long as you do not walk pridefully but instead you walk gratefully (good health), your ok. Ask the Holy Spirit to give you wisdom and understanding and let it be.
In the end, of course the most important excercise is spiritual. We do need to occasionally fast from the dialy routine and just make time with GOD one on one with nothing else in involved. Fasting is important and biblical. GOD does not expect you to spend 9 hours with Him just because you want it to be more than your 8 hour work day. God however does expect you and I to do everything for His glory and with joy. To do everything obediently, according to His will.
