Get hench in 5

There is some research (study here) suggesting that 1 set per body part is as effective for strength gains, as 3 sets.

Make sure that you warm up – get a sweat on

Do each set with perfect technique – fail between 6 and 12 reps. If you can do 12 reps easily, you need to increase resistance
