Xiao Tian looked at this group of special forces soldiers sprawled out in all directions, clearly exhausted to the limit, with some of them already having swollen hands and feet.
After all, the twenty kilograms of iron sand and stones were no joke; even an iron man would find it unbearable.
However, Xiao Tian was very confident, assuring that this group would be back to normal by the next morning! At this moment, Xiao Tian walked directly to the center of the courtyard and blew a sharp whistle.
"Stand up!"
After several whistles, the group of special forces soldiers reluctantly stood up. Many of them were groaning, "Instructor, spare us, if we keep training like this someone might actually die!"
Xiao Tian waved his hand, "Don't worry, I won't have you continue running or doing push-ups. Now, what you need to do is pay close attention to my posture and remember the heart method mantra I will tell you to guide the fatigue within your body."
