Before you start
  • Warm up first with a minute or two of easy walking or marching in place, and cool down the same way after.
  • Wear flat, closed shoes with a good grip, or go barefoot on a non-slip floor if that feels steady to you.
  • Clear the floor around you. Keep a sturdy chair, counter or wall within reach for any move you do standing.
  • Build up slowly. Add repetitions or minutes over weeks, not days. If you take a break, work back up gradually.

Talk with a doctor or physical therapist before you start if you have not been active for some time, if you have a health condition or a worry about exercise, if you have fallen or fear falling, or if a clinician has told you to limit activity. This library is general information, not medical advice.

What you need

A gym machine, with a trained person to show you the set-up the first time.

How to do it

  1. Set a decline bench in the machine so the bar lines up with your lower chest when you lie down, and hook your legs under the pads.
  2. Lie back with your head at the low end, take an overhand grip slightly wider than your shoulders and unrack the bar.
  3. Lower the bar under control until it touches your lower chest, keeping your elbows at roughly forty-five degrees from your torso.
  4. Press the bar back up until your arms are extended, without locking the elbows out hard.
  5. Repeat for the desired number of repetitions, then rack the bar before releasing your legs.

How much

To start: 1 to 2 sets of 8 to 12 slow repetitions, resting 1 to 2 minutes between sets.

As it gets easier: 2 to 3 sets of 6 to 12 repetitions with good form, resting 1 to 3 minutes. Add load or repetitions gradually, no more than about once a week.

How it should feel: The muscles you are working should feel the effort. The last repetitions should be hard but controlled, never shaky or painful.

Tips

  • Line the bench up before you load it. The bar only moves in one plane, so if the bench is a few centimetres out the bar will meet your throat or your stomach instead of your lower chest.
  • Secure your legs under the pads first. Head-down and unsecured, you slide toward the low end of the bench on the first hard rep.
  • Come down and sit up slowly between sets. Long sets with the head below the heart make people light-headed, and this variation is where it happens.

Safety

  • Warm up first, and keep your breathing steady. Breathe out on the effort and in as you ease off. Do not hold your breath.
  • Move with control. Do not lock your joints straight at the end of a movement.
  • Choose a version, load and number of repetitions you can finish with good form. The last few should feel hard but not shaky.
  • Adjust the seat, pads and range so the machine fits your body before you add weight.
More safety notes
  • Start with a light weight and learn the movement.
  • Use the full, controlled range that feels comfortable. Do not let the weight stack drop or bounce.

When to stop

  • Stop and rest if you feel dizzy or lightheaded, sick to your stomach, or unusually short of breath.
  • Stop if you feel sharp, sudden or joint pain. Muscles working hard is expected. Pain is a signal to stop.
  • Stop and sit down if you feel unsteady and cannot settle yourself right away.
  • Call your local emergency number for chest pain or pressure, fainting, or sudden weakness, numbness or trouble speaking.
  • After any of these, do not repeat the exercise until you have talked with a doctor or physical therapist.
  • A pad or handle does not fit and cannot be adjusted.
  • You cannot control the weight through the whole movement.
