To improve your chin ups, you need to
1) reduce your weight
2) improve on your lats
3) lastly, a bit of biceps
To reduce weight, you can go for jogs/runs, or do HIITs (do
google :D )
Do interval trainings as well.
These has the effect of helping you improve
i) Standing broad jump
ii) Shuttle Run
iii) 2.4 km run
To improve on your lats/back strength, do
i) Lat's pull down
ii) Barbell rows
iii) Chin ups themselves, assisted if necessary
To improve on your biceps, I guess most guys should already know
:D
Once you can do 1 chin up, you will improve very fast. Once you
reach about 3 to 4, you might want to add 1 to 2 kg of weights to
yourself and continue training. It will help you improve even
faster.
