Hi, im starting to do squats as i can do them during the day while using the computer (taking a 1-2min break a few times during the day) but i feel they are working my legs and not my glutes, or maybe my lower back even, I must be doing something wrong because i heard they are good for the glutes aswell
Your body will generally compensate for muscle weaknesses by having other muscles make up for the deficiency, and/or limit your range of motion for certain movements.
While weights are preferable, you should be able to get some mileage out of bodyweight exercises. Glute bridges are a classic for glute activation, and they require no equipment.
