Is Rest day from workout needed to maintain?

Currently I'm trying to maintain my weight. I've been working out daily. Going to the gym to bike for 20-40minutes( depends on how much time I have on that day), 5-10minutes on the stairs climbing machine and lift light weights for 20times in weekdays and light aerobics for 30minutes on weekends. I wonder if rest day is needed for muscle recovery... Do you guys have rest day? Do you workout as much as when you were trying to lose weight or the same?
Now I also climb stairs to my classroom 4th storey around 3rimes a day and climb stairs back home (6th storey) and walk to my school.

Edit to add.

For anything other than pure cardio, you need a day or more per week to let the muscles recover (depending on how hard you've worked them). And it's a good idea to have a "Lazy day" from all exercise anyway. But actually, serious workouts slow down weight loss progress more than they do help it, at least in the short-term. But since you're maintaining, you should find it easy to stay in a happy medium.

rest is neded to rebuild strength. rest is needed to give nervous system time to recover. rest is needed.

^^^^^This

I usually have 2 rest days per week, but when I work out I work out hard. My muscles definitely need the recovery time and I need the lounge time. Honestly, sometimes I even take three rest days if my schedule is crazy. It hasn't hurt anything and I like those days when I get to sleep in or spend time with friends. For me, it's all about balance.

I rest 2 days aweek-use to do 7 days aweek had to find a balance-because I lift I need my muscle to recover-I do try to get some type of cardio in daily even if its running are a fast wlak-as for strength training 5 days aweek for sure-body need to rest

Yes, I have 2 rest days a week.

Today is my rest day. However I will still be moving around. I have to work and I am on my feet for 7 hours at work. Still moving, lifting and bending. But since this is my daily life, my body is use to it.

Tomorrow I will hit the gym again. I am now trying to do 2 days on and 1 day off. It is always going to depend on my schedule.

here is my plan

Day 1 - 30 min. circuit weights
30 to 45 min. of cardio

Day 2. Tummy weight work out
30 to 45 min. of cardio

Day 3 rest

Day 4 - Same as day 1

Day 5 - Same as day 2

Day 6 Rest

Day 7 cardio ONLY

I've found that yes, a rest day is needed. It'll help you recover!

I'm doing SL5x5 and training for a 10k. Currently my schedule is:

Monday - Run (Zero to 10K program)
Tuesday - SL 5x5
Wednesday - Run
Thursday - SL 5x5
Friday - Run
Saturday - SL 5x5 in the morning, roller blading in the evening
Sunday - REST

I've come to appreciate my rest days!

I have 2 rest days per week...it is rest from vigorous exercise or otherwise activity that would tax my body. I don't sit on my *kitten* and do nothing...that is stupid IMHO. I tend to walk a lot, one of my rest days is always on a weekend and I take my boys to the zoo or aquarium or some museum or whatever...I just don't do anything vigorous or "structured" exercise, I just move my body. I've been maintaining for almost a year now...really, exercise is great for your overall health but your fitness regimen needs to be something you can do week in and week out pretty much the rest of your life...working out 7 days per week is not sustainable in the least and frankly completely unnecessary. You "burn" calories 24/7 and your body needs a break...exercise is good for you but also pretty hard on the body if you're doing anything moderately intense.

Do you need a rest day if you are just walking every day at over 5KMs/day?

No.

On rest day, do you really not do any exercise?

Sometimes and sometimes not. I generally work really hard and earn my rest days so I don't feel guilty about taking a full day off with no exercise. I know my body needs it and it will benefit my progression in the long term. Having said that, if I feel like it I will often go for a gentle walk. This can actually be quite beneficial as it can increase blood flow to areas that need it and also loosen you up.

ETA: for me walking isn't really exercise (well it's exercise but not training) as it doesn't raise my heart rate enough to count. For some people starting out walking will challange you enough to be your main source of exercise and that's okay as long as you push yourself a little and progress.

Looks like you are just doing light cardio. You don't need a rest day. None of those activities would stress your CNS (central nervous system).

When you are lifting heavy weights or going HIIT (High intensity interval training), then you would need rest days in between.

If you eat well (protein, some carbs) then you definitely don't need rest days.

I lift weights 4x a week. I do minimal exercise 2x a week (no weights, just walking or maybe a HIIT session), and 1x a week I do NOTHING (on Sundays). It is necessary for me to be able to start the week not feeling sore or tired.
