Just a quick post on this subject because I for one am guilty of overdoing the gym sometimes, especially when I start to see some gains! I’m not saying you should overthink training and rest periods, but I would suggest respecting them. Despite the benefits of exercise, too much can increase the physiological stress placed on your body, and sometimes this can be too much for your body to deal with.
If this stress is allowed to persist, then the strain may manifest as impaired immunity and/ or inflammation, and the consequence of this is overall diminished resilience to stress (such as that from training), meaning your body will refuse to adapt anymore. This is known as ‘blunted reactivity’ which in turn halts, and even reverses your gains! Not good!
Be sure to allow adequate rest, maybe 1 or 2 days a week of minimal physical activity, as well as being sure to meet your nutritional requirements. A Multi- vitamin and mineral may do the trick, so too would a good source of protein, such as Whey protein.
