A softer midsection can become more noticeable after 65 as body composition changes and muscle mass drops. Exercise can help by building core strength and increasing how much work your body does throughout the week. It won’t tighten loose skin on its own, but it can improve the shape and support underneath it.
Crunches only train a small part of the picture. Getting the legs involved, raising your heart rate, and working the core in different positions gives you a much better setup for fat loss and muscle retention. Pair that with solid nutrition and enough daily movement, and your midsection has a better chance to change over time.
The couch makes all of that pretty easy to set up. You can use it for incline core work, turn the seat into a squat target, and finish with more direct ab exercises without needing much equipment. The five moves below mix strength and conditioning so you get more from the session than another round of crunches.
Couch Plank Hold
Start with a basic brace and make your abs work without any spinal flexion. The couch angle takes some body weight off the plank, making it easier to hold a good position and build time under tension.
Muscles Trained: Abs, shoulders, chest, glutes.
How to Do It
- Place your hands or forearms on the couch.
- Step your feet backward.
- Form a straight line from your head through your heels.
- Brace your abs.
- Keep your hips level.
- Hold while breathing normally.
Recommended Sets and Reps: Perform 2 to 3 holds of 20 to 40 seconds. Rest for 30 to 45 seconds.
Best Variations: Higher couch plank, forearm incline plank, longer plank hold.
Form Tip: Keep your ribs stacked over your hips during the hold.

Incline Mountain Climber
This one raises the pace while keeping the core involved. Each knee drive asks your abs to stay engaged as your legs move, and the faster rhythm turns the exercise into a short conditioning interval.
Muscles Trained: Abs, hip flexors, shoulders, chest.
How to Do It
- Place both hands on the couch.
- Step your feet backward into an incline plank.
- Brace your abs.
- Drive your right knee toward your chest.
- Return your foot to the floor.
- Switch sides and continue alternating.
Recommended Sets and Reps: Perform 2 to 3 rounds of 20 to 40 seconds. Rest for 30 to 45 seconds.
Best Variations: Slower mountain climber, alternating knee drive, faster mountain climber.
Form Tip: Keep your torso steady as your knees move.
Box Squat Intervals
Engaging your legs gives the workout more muscle to work. Squat intervals can raise your heart rate while strengthening the thighs and glutes, making them a better fit for overall fat loss than spending the same time on crunches.
Muscles Trained: Quads, glutes, hamstrings, core.
How to Do It
- Stand in front of the couch.
- Set your feet about shoulder-width apart.
- Reach your arms forward.
- Sit your hips back and bend your knees.
- Lightly touch the couch.
- Stand and continue at a steady pace.
Recommended Sets and Reps: Perform 3 to 4 rounds of 30 to 45 seconds. Rest for 30 seconds.
Best Variations: Slower squat interval, higher couch squat, bodyweight squat without the couch.
Form Tip: Touch the couch lightly instead of sitting down between reps.

Couch Flutter Kick
Flutter kicks give your abs more direct work while the couch offers a comfortable place to set up. The challenge comes from keeping your pelvis controlled as your legs move, so shorter kicks can work better than swinging through a big range.
Muscles Trained: Abs, hip flexors.
How to Do It
- Sit near the front edge of the couch.
- Lean your torso back slightly.
- Hold the couch beside your hips.
- Extend your legs in front of you.
- Lift one leg as the other lowers.
- Continue alternating with controlled kicks.
Recommended Sets and Reps: Perform 2 to 3 rounds of 20 to 30 seconds. Rest for 30 to 45 seconds.
Best Variations: Bent-knee flutter kick, shorter-range flutter kick, longer interval.
Form Tip: Bend your knees more if your lower back starts taking over.
Couch Knee Tuck
Knee tucks finish the routine with a stronger abdominal contraction than the plank work you started with. Bringing the knees toward the torso shortens the abs under tension, while the couch gives you something stable to hold as you control the movement.
Muscles Trained: Abs, hip flexors.
How to Do It
- Sit near the edge of the couch.
- Place your hands beside your hips.
- Lean back slightly.
- Extend your legs forward.
- Draw your knees toward your chest.
- Extend your legs again and repeat.
Recommended Sets and Reps: Perform 2 to 3 sets of 8 to 12 reps. Rest for 30 to 45 seconds.
Best Variations: Single-leg knee tuck, smaller-range knee tuck, slower knee tuck.
Form Tip: Keep the movement controlled instead of swinging your legs.

Give Your Midsection More Than Crunches
Use this routine two to four days per week and let it support the bigger habits that drive fat loss. The exercises can strengthen your abs and increase total activity, but your waistline will change most when the rest of the week lines up too.
- Keep walking regularly: Extra daily movement helps raise total activity without adding another hard session.
- Progress the intervals slowly: Add time only when you can keep the reps controlled.
- Keep strength work in your week: Holding onto muscle becomes especially important during fat loss after 65.
- Watch overall food intake: A sustainable calorie deficit still drives body fat reduction.
- Keep protein consistent: Adequate protein supports the muscle you’re trying to maintain.
- Track your waist over time: Give the plan several weeks before judging whether it’s working.
