If you are out running, cycling, or walking the dog these dark, gloomy winter evenings, pull on a pair of LED (light-emitting diode, duh!) gloves. They're warm, wind- and rain-proof, and, best of all, they contain an LED strip that you can activate (to flash, or to stay on permanently) at the flick of a switch to make yourself visible up to a mile away. Nathan LED Polar Fleece Gloves, £29.99, 01923 242233 for stockists (1000mile.co.uk).
Weigh to go
Few of us emerge from the festive season the same size as we entered it, but new research has found that daily weighing - all but outlawed in diet circles these days - might be an effective antidote to weight gain. A group of first-year female students at Cornell University in the US were weighed at the start and end of a semester, while another group weighed themselves each morning. The first group gained an average of 7lb (around 3.5kg) over the semester, while the daily weighers did not even gain an ounce. David Levitsky, professor of nutritional sciences and psychology at the university, says that plotting your weight daily for a week is enough to prevent overeating. Happy Christmas to you, too, professor.
Once is enough
Not content with sharing a name with a Roman military commander, Mark Anthony claims two further USPs with his new fitness DVD. First, you need to do it only once a week; second, it comes in male and female versions. That once-a-week claim is a bit of a con, really, because you're meant to combine the DVD's strength workout with three cardiovascular exercise sessions, which you do under your own steam - besides, all the evidence says you need to strength train two to three times a week for best results. As for the division of the sexes, the main difference seems to be the sex of the models (which I'd say they got the wrong way round - pouty girl for the ladeez, strapping guy for the blokes), though the exercises do vary a bit, too. My main complaint, other than the appalling background music, is the fact that you feel as if you are watching Mark give his models a personal training session, rather than as if he's telling you what to do.

I've had a rude awakening. Preferring to run on time, rather than bothering too much about distance, thanks to my Navman Sport Tool GPS device I've just found out that my 'Oh, it's about 10 miles' run is actually 6.7 miles. I'm still sulking, but I am mollified by how simple the Navman is to set up and use. I so lost patience with the calibration procedure of my last measuring thingy that it ended up in a drawer. Strap on a Navman and you can tell at a glance your speed, time, distance, average and current pace. Read it and weep. The R300 running model, £99, 01978 729941 for stockists (sport-tool.com).
