I am focusing on toning right now as well as maintaining my weight. What percentage of my workout time should I be devoting to cardio versus weights? I usually spend 5-ish hours in the gym per week. Thank you!
I wouldnt look at it so much in terms of time as much as I would WHAT you are doing.
As for the strength training, there is no time limit- its all about what you do and what muscle groups you hit. Each strength training session you do needs to hit all 10 major muscle groups, and don’t work the same muscle group two days in a row (it needs time to rest or you risk injury.) To read more on strength training requirments read my posts Don’t Over Think It and How to Up Weights and Reps.
Basically, now that you are maintaining all you need to do is the requirements for health: about 30 minutes of moderately intense cardio most days of the week (5-6) and strength training (making sure to hit each major muscle group) 2-4 times a week.
