On my journey of fitness, I have to consistently remind myself it is necessary to have a rest day. I know and have heard of many people who workout 7 days a week consistently unless an illness or matter of emergent.
It is necessary for the body, muscles to rest as working out with weights everyday and muscle building, the muscles retain water. The body needs to relax and allow the muscle to release. Now I am one sometimes, require proof and seriously I thought this was another workout lie. However, I have noticed my day of rest allows me to continue my journey of fitness with progression instead of as previously I would lift the same weight in pounds and add maybe one or two more reps. Yes, my body would indicate I can increase but my reps would decrease.
Today if I am fatigued or feel as if I am unable to increase my weights for a specific number of reps, I will stop and use the previous weights but continue to increase. This has helped my workouts (when working out with weights). I also include HIIT and Cardio in my workouts. Ultimately I say choose the number of days of workout that suits your body and how your body response.
Whatever choice you make, have fun and keep up the great workouts…To a healthier you, much love.
