I've started the following light excercising regimen:
- light warm-up (~10 min);
- a 5 short sets of pull-ups (around 16 total);
- some jumping and few sets of 50-60 mountain climbers in between of pull-ups;
- couple minutes of jumping jacks and some stretching after;
- the goal is to improve in pull-ups so they are done up to fail and improvement is being achieved;
This happens once in 4-6 days with few yoga sets and ~1 long walk in between.
I feel considerably fatigued on a post-workout day (usually cut any activities) and then may feel fatigue "tail" up to few days more. By fatigue I mean mostly mental fatigue - drop in concentration and early tiredness in mental activities/studying, irritability. Physical component is felt to lesser extent.
I also tried to do some squats once in between (around 20-30-20), but finally gave up because it made things much worse.
I'm 33y.o. and around 68kg weight. Am used to have lots of physical activities like hiking, swimming etc. from time to time and always felt fit enough.
Can that level of fatigue be normal, or should I look for other reasons?
