I used to go to the gym 4 times a day, but then academic circumstances led me to discontinue my schedule for an entire year or so. Two weeks ago, I was tired of losing my gains and becoming fat, so I just started doing 15 pushups and 30 squats (weightless) every single day. And I have to say, even doing these basic movements actually have made a noticeable change.
My biceps look bigger and even my forearms have developed. My chest fat has decreased, and even my gut looks leaner.
Should I keep doing this exercise with little incrementals per week or should I start adding sets to these?
