I’m a big fan of bodyweight training! In fact for the last year I have almost exclusively trained by bodyweight doing hiit, low-impact, yoga and a bit of weighted backpack lifting on the side. Here are 4 of my favourite upper body exercises.
I would typically combine these with a few (2-4 depending on client level) of my other favourite exercises and try them out for 30-45 seconds with 10-20 seconds rest. I would usually do this 1-4 times through, again, depending on level.
I hope you enjoy and if you try them out, let me know how it goes and how you integrated them into your routine!
