I want increase my endurance with bodyweight exercises including pull-ups, push-ups, sit-ups etc.
Would it be better to use progressive overload and start at, for example: 3x4 reps for Pull-ups and progress by an extra rep per set every day until I get to my max (say 3x8) and then rest for a day and resume...
or...
grease the groove: do single sets of low reps (for example 3 reps a go) throughout the day. So for example, every time I walk into my room, do 3 pull ups.
or...
a combination of the two: grease the groove with 2 pull-ups a go on the first day, 3 pull-ups a go on the second day, 4 on the third etc. until I reach the point where I'm doing 1 under my max every day and then have a day or two rest and resume?
Also, from what I've read about greasing the groove, it's just making your muscles more efficient - so surely gtg will only work for a certain period of time before you're muscles are as efficient as they can be - maybe then is the time to swap to progressive overload?
