One thing that comes up time and time again is that fitness and pushing yourself beyond your limits isn’t so much limited by your physically capabilities but more your mental attitude.
The first time I tried burpees I was convinced I couldn’t do them! I managed 3. I can do them (in a fashion). I remember the first time I managed 10 in a row. That feeling was unbelievable, you’d have thought I’d hit the jackpot on the lottery, then the time I managed 45 burpees in 1 session I had a smile on my face for hours after. But if you’d have told me that first time I could do 45 in one session I’d have said “no way!”. Sometimes when I am doing something like burpees I mentally have to tell myself I can. Outwardly I will vocalise “I can’t do this” but in my head I am trying to tell myself I can. It is a real mental battle sometimes. But it is good for me to reflect back and remember what I thought I couldn’t do and where I am now to see that pretty much anything is possible.
Now I remember this “concern”. It is the same concern I had about doing regular burpees right at the start all those months ago. I got past that mental hurdle and I don’t really think about it now. So I just need to convince my mind that I CAN do kettlebell burpees and that I WON’T deck it.
