Want a fitness model body? Our January cover model Andréa’s Albright shares her bikini blaster tri-set.

Andréa Albright's bikini blaster workout - PICTURE - Women's Health & Fitness

The rules: A tri-set is simply three exercises back to back. 

1. Walking lunges

Start by doing lunges across the room. No weight is needed. This just gets you warmed up and the blood moving.

2. Chair step-ups

Next comes step-ups on a stable bench or chair against the wall, doing 10 to 15 reps for each leg.

Do not alternate legs; this keeps the tension on the glute and thigh muscles.

This is what I call The Time-Tension Principle™ which gives you more results in less time. This increases an enzyme in your body called AMPk as well, which helps burn even more fat.

3. Bridge pose

Finish off with bridge pose, taking long, slow, deep breaths. This calms you down while tightening and toning up the butt and thighs.
