You are going to alternate between repetitions of push ups and triceps.
Drop and give me 20 push ups (yes, it can be off your knees)
Now, do 20 tricep dips
Then 10 push ups and 10 tricep dips
5 push ups, 5 tricep dips ... you're done!
Do this every day and I promise you will thank me later :)
This WILL get easier, and when it does, bump it up to 30-20-10 Reps!
