Thankfully, research shows that you maintain some of the strength you gained before you stopped training. The number of muscle fibres used during exercise decreases by around 13 per cent after just two weeks of no training — though this appears not to be accompanied by a decline in muscular force. This implies that the losses observed across the longer periods of detraining are a combination of both this initial decline in the number of muscle fibres we use but also the slower decline in muscle mass.
For the average gym goer who lifts weights, they would experience a drop in the size of their muscles — over time finding it harder to lift heavy loads as they have fewer muscle fibres being recruited.

We all familiar with the dedication, persistence and consistency that have to achieve our aspired fitness goals. But after all that hard work, how long does it take for us to be reverted back to being a couch potato? It turns out that despite the immense effort we put into training previously, taking a bit of time off means that we become unfit astronomically faster than it took us to actually get in shape.
The key to becoming fitte r -- whether that's improving our cardio or muscular strength -- is to exceed "habitual load. The stress that this has on our body has allowed us adapt and overcome the increased load, allowing all of us to ascend to higher levels of fitness.
Let's take a look at cardiovascular fitness. Cardiorespiratory fitness is indicated by a person's V02 max the amount of oxygen a person can use during exercise. Some of us might not know that it takes just less than 8 weeks to drop back to where we started off.
Plasma and blood volume decrease due to the lack of stress being put on our heart and muscles. Strength Training. Studies have shown that in the average person, 12 weeks without training causes a significant decrease in the amount of weight we can lift.
The reason we lose muscle strength largely has to do with the fact that we're no longer putting our muscles under stress. A study in mice has led researchers to further explore how hormones influence the brain and motivate the body to move, with women often becoming inactive after menopause, when estrogen fades.
