How do I prevent sore wrists whilst doing my weight lifting routine?

I’ve been lifting weights on and off now for over a year. I have found that when I am on and doing my workout 3x a week I end up with sore wrists all the time.

My routine consists of a total body workout, which includes 20 to 30 push ups. In between each muscle group I do: 30 step ups, 50 push ups with a 30lb weigh on my chest, 20 mountain climbers, 20 burpees and 20 kettle bell swings with a 30lb weight.

I know the push ups, sit ups (but only because of the weight), mountain climbers and burpees are what cause my wrists to eventually scream at me. But I don’t want to give that part of my workout up. I’m not breaking my wrist when I lift my weights so that isn’t a problem.

I’ve just come off of a 14 day break and my wrists are pain free. I’d like to keep them that way.

Any suggestions?
