Glute Bridge
This is a great bodyweight exercise to help warm-up the glutes and several muscles prior to incorporating more range of motion and any weights. You can enhance a glute bridge with resistance bands, and really make sure that you engage your core in addition to your glutes. Start with a regular glute bridge and work your way up to the single-leg bridge, which is very effective because it targets your hamstrings, glutes, and core.
Step Ups
Look for a durable box or sturdy bench to bang out some low-impact step ups. This move is great for balance, stabilization, and building strength. Hold some weights or detergent bottles on either side of the body for extra resistance.
