If you are in a gym, each day you likely do different exercises to work on different muscle groups (pectorals, back, biceps, etc.), but what happens if you do the same exercise every day of the week?
When we exercise we apply pressure to our body to strengthen it. However, believe it or not, the results of any training are achieved during rest. After exercise, when the muscles are inactive, a recovery period begins where they adapt to physical activity.
So when we create an exercise routine, we exercise different muscles each day, giving them some rest time to recover. This changes if we do the same exercise every day.

Let's say you want to go for a run seven days a week. All this activity puts pressure on your legs, especially on your knees. If you don't rest properly, your muscles will start to break down, and you won't get the same results.
It does not matter if you do a low-impact sport. The best thing that you can do is to rest the different muscle groups for one or two days. There are many exercises you can do to avoid falling into a boring routine.
The most important thing is that you keep doing some physical activity during the week, but without exceeding the limits of your body. Staying in shape is a process that takes time and dedication, so you shouldn't rush to reach your goals.
