That rock had around 30kg ๐๐โค๏ธ I usually lift 30kg dumbbells in one hand overhead but this one had bad gripโฆ I used to train with rocks steel and bottles of water back in the time there isnโt perfect technique or exercise itโs everything about movement and using muscles. Even if you donโt know how to train and have bad technique you might be beginner itโs still better to train and move than laying on bed ๐ช๐ even if you might get injured from doing something with bad technique you would need to push too heavy and itโs bigger chance you will get injured and sick ๐คง from not training at all
So bad movement still better than none
