should I take a break from exercise?

Taking one or two days might help your muscles recover, but a week would probably have you losing too much fitness.

Taking a week off wouldn't hurt.

Reading your other posts...You probably do not need to lose weight, you may want to look into body recomposition.

I can think of 2 good reasons to take a break: 1) if you're burned out, take a few days to recouperate. 2) If my weight loss has stalled with my normal diet and exercise plan, sometimes I change it up a bit. Over the course of 1 week I'll eat more, eat less, not work out, then work out a bunch - just try to keep my body guessing. It might not work for everyone, but my weight loss stall went away and I could resume my normal 1450 cal/day and exercise again.

For me, if I take a week off it's hard to restart. Plus, by the 4th day of inactivity I have a lot of trouble sleeping.

Why don't you try taking a couple days off (other than walking), and see how you feel?

This is a perfect example of body recomp....she lost the weight doing cardio and still didn't like how she looked...she started lifting heavy.

I do workouts on fitness blender, weights of 15-25 lbs not really heavy or anything.

Take your measurements and progress photos before...When I started this program within 3 months I had lost inches everywhere! 2" in my legs.

If you can't get to lifting heavy yet, look into convict conditioning. It's a lot of body weight exercises.

Another awesome resource here...
