What is your goal? Do you want to be slimmer to wear a size smaller clothes? Or you want to get more strength, lean muscles? Or are you sitting all day and you have sore back and need to work on to stronger core?
Probably the best way to get weight loss, lean muscles, build strength, get better posture and so many other reason is why kettlebells are so great! Actually the kettlebell is just a piece of iron but the StrongFirst system how we use it makes it magical!
