30 is not even close to the end.
I am 32 and BY FAR, am in the best shape of my life. I have more muscle and less fat than I ever have and I feel great. The only time that comes close would be my senior year in high school, but I was a twig, I just had better cardiovascular endurance.
James 1:16-17 ESV
Do not be deceived, my beloved brothers. Every good gift and every perfect gift is from above, coming down from the Father of lights
With God's help...Mens sana in corpore sano
