Work is very important to me, but it's very mentally demanding. If I'm tired from working out my work suffers.
I've taken a break from the gym for the last few months, and have noticed improvements in energy and therefore the results I am getting at work.
I want to start training again. How can I start training hard without affecting my work? I haven't been able to find a balance yet by just eating more and sleeping more. At this point in my life, work is the higher priority.
If you are looking to increase your cardiovascular(vo2max) you could do high intensity interval instead of long training session.
Life tends to shift in the direction of our priorities. If you make exercise a priority then other areas of your lifestyle will have to adapt.
That said, you can still find a balance of a healthy amount of training that you can manage and still have great energy levels to put towards work. Exercising can even help enhance your productivity and has be shown to do so in studies. If you go for a short run or do 20 minutes of body weight exercises each day you can still maintain and even improve your fitness and raise your energy levels!
Good luck and let us know how it goes.
Maybe you are over exercising. I like to do less than I want so I'm not overtired and I'm always looking forward to tomorrows workout. Just 20 min at a time is respectable.
Maybe do it after work or just start out slow with your training and build it up. If you're tired from training to the point where it affects your work, you are probably over training.
Instead of going to the gym for hours, do HIIT (high intensity interval training) workouts. I've been following Zuzana Light for years, working out daily, great results in only 15 minutes/day. Just don't listen to her diet tips.
It sounds to me like maybe you were over-training which is what so many people do! rest is a really important part of training! Maybe approach training from a "train smart not hard" sort of perspective. I know it feels good to give it your all, maybe limit that to weekends.
