There are no set class times tomorrow evening. Show up before 7PM in order to have enough time to do your lifts. Please make sure you get adequate time to warm up. Please figure out your target weights before you come into the gym.
The CrossFit Total is the sum of the best of three attempts at the squat, the press, and the deadlift… There is no time limit for each lift or for the length of the session in which they are all performed, but they must all be performed during one session—i.e., you cannot leave the area to rest or perform other activities between the three lifts.
The first attempt would be a weight you know you can do for a heavy set of three. The second attempt would be a weight you know without any doubt that you could do for a single, having just done the first attempt. And the third attempt is the weight you want to do, based on your performance on the previous two attempts.
