This 10-minute walking-strength workout builds stronger legs without weights ...
A 10-minute standing routine from a CSCS trainer to rebuild leg strength after 65, using just a chair and mini-band.
I like to exercise for the benefits it brings me, but I could really do with it taking less time, so I set about finding out how expert trainers would work out if they only had 10 minutes.
Set a timer for 10 minutes. Perform each exercise for 45 seconds, then use about 15 seconds to switch positions and reset.
