If you're looking to chisel those arms without spending hours in the gym, this 15-minute bi tri workout is your new best friend. Forget the endless curls—this quick but killer routine targets both your biceps and triceps with efficiency, so you can get in, torch those muscles, and get on with your day. Whether you're squeezing it in before work or blasting through it during lunch, this routine delivers serious results without the marathon session.
Why Bi Tri Workouts Rule
Your arms aren’t just for show—they’re essential for everyday movements, from lifting groceries to hoisting kids (or pets) off the floor. Focusing on both biceps and triceps ensures balanced strength and definition. Plus, strong arms help with bigger lifts like bench presses and pull-ups, making this workout a smart addition to any fitness plan.
The 15-Minute Blitz
No fluff, just fire. This routine alternates between biceps and triceps moves, keeping tension on the muscles while minimizing rest. Grab a pair of dumbbells (or improvise with water bottles or resistance bands) and let’s go.
1. Hammer Curls (Biceps)
Stand tall, weights at your sides, palms facing in. Curl both dumbbells up toward your shoulders, keeping your elbows glued to your sides. Lower slowly—no dropping! Do 12 reps, then move straight into the next exercise.
2. Triceps Dips (Triceps)
Use a bench, chair, or even the edge of your couch. Hands shoulder-width apart, fingers gripping the edge. Lower your body until elbows hit 90 degrees, then push back up. Keep it controlled—no bouncing. Aim for 10-12 reps.
3. Concentration Curls (Biceps)
Sit on a bench or chair, legs spread. Rest one elbow against your inner thigh, curl the weight up, and squeeze at the top. Lower slowly. Do 10 reps per arm.
4. Overhead Triceps Extension (Triceps)
Stand or sit, holding one dumbbell with both hands. Lift it overhead, then lower it behind your head, bending at the elbows. Press back up. Keep elbows in—no flaring. 12 reps.
5. Zottman Curls (Biceps & Forearms)
Curl the weights up palms-up, then twist your wrists at the top so palms face down as you lower. This sneaky move hits both biceps and forearms. 10 reps.
6. Diamond Push-Ups (Triceps)
Hands close together under your chest, forming a diamond shape with thumbs and index fingers. Lower your chest toward your hands, then push up. Modify on knees if needed. 8-10 reps.
