Hitchhiker’s guide had it right, all you need is a towel.
I have used it to add intensity to my sandbag/bodyweight workouts
to do isolation movements, curls, triceps extensions
and all kind of grip training (you can never have to strong of a grip).
Cinder blocks weigh in at around 20-40lb, have convenient holes in them and are usually being thrown away at any construction site.
Don’t forget to do your pullups!
Over a branch or railings. The towel creates a forgiving grip were needed so not to tear your hands to shreds and strengthens the grip.
Wrap the towel in a thick bundle and hold for time.
Tie a solid knot and lean back as far as you can for time or do rows, it’s hell on the forearm.
For a quick 20-40 min workout I’ll go running with a towel and scan for spots to do pullups, extensions, pushups, pisolsquats 8-15reps at every stop for 3-6 stops in total.
Be creative and get some work done!
Train for life.
