You probably haven’t done a bear crawl race since you were in fourth grade.
You’ll find that it’s pretty demanding if you try it.
You probably can’t do a set of ten strict push-ups, pull-ups, dips, & squats with full range of motion. (At least, today.)
These are exercises that you don’t need a gym membership or any equipment for, but, if practiced correctly & often, will transform you.
And, if you love weights, or already belong to a gym, you can keep it simple there too.
No fancy new machines, no ‘new’ technology needed.
Squats, presses, deadlifts, cleans, and rows … they aren’t ‘fancy’. They just work.
Basic, simple exercises get results. Period.
