Do it until you can't anymore, don't count just do it everyday until you can't anymore

You don't have to do it everyday maybe alternately or maybe every threedays so your muscles will rest and grow (also take up some protein). Try to increase it overtime.

Here's an example

Day 1: 20 Now

Day 4 21 One more

Day 7 22 AGAIN

Day 10 23 One more

Day 13 23 (ouch you couldn't do 24)

Day 16 25 (you could still do one more :D)

Day 19 25 (no increase)

Day 22 24 You became a lil weak

Day 25 26 Strong!

Day 29 28 You skipped some days but you noticed you got more stronger

Day 33 29 Yeah. You felt very energetic to add one

Day 36 30 You reached 30

keep on raising to now 30... here is a tip do 3 series

you know do 20 now, rest 30 seconds, do more 20, rest 30 seconds and do that again

This will maximize results
