The few Pilates mat exercises we have seen lately are all great pieces to practise EVERYDAY if you want to have a stronger and flatter abdominals. This one is really good for your lower abs and I think is a great piece to include into your pilates workout. I would strongly encourage you to get better with your single and double leg stretches first before practising this piece. Most people have a tendency to arch their lower back in this piece which we do not want to. This is great but if you do not do it properly you may get back aches.
