Equipment comes next. "For corporate gyms, the emphasis is on cardiovascular equipment, as those serve the basic needs of fitness," says Sachdev. Apart from the treadmills and cross-trainers, the steppers and exer-bikes are popular.

"A lot of attention is paid to acoustics, with special emphasis on floors not being noisy," says Ritu Duggal who, along with Anisha Johri, designed BOC India's gym in the Taratala office.

After sound, the stress is on sight. "This is a place where employees come to relax and so it should be bright and cheery," adds Duggal. The BOC gym, with mirrors galore, is dominated by colours blue, pink and purple.

A multi-station gym, on which four people can exercise simultaneously, is also popular with office gyms.

A new product now catching corporate fancy is the aqua rower, which gives the effect of rowing a boat.

"But how much time should I spend at each station?" asks Suhel Sampat, a 25-year-old IT professional with a gym at his workplace.

With employees spending an average of 30 minutes in the gym while at work, at least 20 minutes should be spent on the treadmill and another 10 minutes doing strength training, like the bench press, feels fitness consultant Anwar Wahab. He also advocates structured regimens that can be fitted into 20-minute or 10-minute cycles to utilise small breaks between work sessions.
