To do this workout, all you need is a pair of adjustable dumbbells (or access to a nice db rack.) If possible, choose a weight that allows you to do all 3 exercises without stopping to change the weight.
Here is the workout. Perform all 3 exercises back-to-back with no rest in between. After each cluster, rest 1-2 minutes. As soon as you are ready, jump into the next round. Do 3-5 rounds depending on your fitness level.
Floor Press in Bridge
Get into a hip bridge on the floor with the dumbbells held tight to your chest. Press the dumbbells in a straight line while keeping the glutes tight and the heels pressed into the floor. Don't let the hips sag when you lower the weight. Do 20 repetitions.
