Until your Dip Belt ships, the obvious choices to replace Dips and Chins are
Machine Bench Press
Rows of All Sorts
Weighted “Dogg” Chins.
To do a “Dogg” Chin, you’ll need a training partner, a rack or a smith machine, an adjustable bench, and some weight.
Set the barbell in the smith machine or on the safety pins at about neck height. Hanging from there, you’ll put both your feet up on the top of the incline bench. Your body should obviously be in a V-shape. Have your training partner place a dumbbell in your lap with you hanging there. Now, knock out some reps. When you finish the set, you’ll need your partner to help you get the weight off.
You can also just do Dips and Chins by holding dumbbells between your thighs and crossing your legs. It’s really not that hard to do.
This might be a good time to switch things up and do Military Press and Rows instead of Chins and Dips.
