Is it reasonable to work-out 7 days a week doing strength-training, provided the muscle groups are cycled each day with sufficient rest between each training, or will this be detrimental long-term?
Additionally, would working a sedentary desk-job affect this (e.g. can this be considered 'adequate rest' through the week)?
If it makes any difference, my motivation is for both weight-loss and for muscle-gain.
I typically go to the gym for an hour, with a routine of 30 minutes strength-training, and 30 minutes cardio. The strength-training always targets different muscle groups each day (e.g. chest, back, core, legs, arms, etc) -- and I normally try to cycle it such that the same muscles won't be reused back-to-back to allow as much rest in between as possible. The workouts are normally mid-to-high level intensity.
Most recently, I've been making an effort to do this daily as opposed to my old routine of going 5 days a week -- but I want to ensure that this won't have negative consequences to myself in the long-term.
So far, I have not experienced anything negative yet. In particular:
- I am still seeing improvements in my overall weight-lifting
- I am still losing weight consistently (to be expected, since I will continually be burning calories)
- I am not in any pain when I do this (since I target alternate groups)
However, there have not been noticeable differences in muscle-mass according to my Fitbit Aria 2 scale (whose accuracy I don't entirely trust). Additionally, I have found many articles saying to rest at least one day a week -- however these articles never seem to address the cycling-muscle-group approach.
One additional motivator for this question is that I work a desk-job which keeps me pretty stationary for ~8 hours a day during the week, and so I'm unsure if this could reasonably be considered a form of rest throughout the day (contrast this to someone who might be doing a high-intensity job that involves carrying heavy objects).
Any insight into this would be appreciated
